DNA: THE BLUEPRINT FOR LIFEDNA: THE BLUEPRINT FOR LIFEDNA (deoxyribonucleic acid) is a double helix made up of millions or billions of the nucleotides Adenine, Cytosine,
Guanine, and Thymine.
It is subdivided into dozens of chromosomes, each of which may contain thousands of genes. The genes are made up of
thousands of the nucleotides A, C, G, and T.
By using these in many different combinations, DNA can spell out the instructions to produce any type of living thing.

FUNCTIONS OF DNAFUNCTIONS OF DNA
1. Cell Repair and Maintenance. DNA contains the instructions to put together hundreds of amino acids into each of the thousands of types of proteins the cell needs to work properly.
2. Cell Reproduction. It contains the instructions to link those proteins into a complete cell, as well as to reproduce itself so that offspring can also function properly and reproduce.
3. Survival and Diversity of the Kind. DNA contains far more genes than are visibly expressed in any individual. Unexpressed genes are available to pass on to future generations.DNA can carry so much extra information that if one breeding pair had the right combination of genes, they could produce an entire kind containing multiple species and breeds.

WHAT EVOLUTIONISTS ARE OVERLOOKINGWHAT EVOLUTIONISTS ARE OVERLOOKING
DNA is a form of communication – a language written in chemicals – that specifies how to make a living thing from other chemicals.
1. All known communication starts with an idea. 2. The idea is then converted into syntax and grammar in order to
be expressed.3. Once the syntax and grammar are expressed in words, THEN the
idea is converted to letters and symbols to convey the message.First comes the concept, then the grammar, then the letters. But evolutionists believe the letters of DNA (A, C, G, T) came first, then accidentally arranged themselves into triplets, then
into genes, then the genes accidentally came together into meaningful instructions for how to produce living things.

TWO MAJOR TYPES OF GENESTWO MAJOR TYPES OF GENES
HOMEOTIC: Common to all members of a kind. Responsible for structures characteristic of the kind and often crucial to life. (Heart, lungs, eyes, etc.) All homeotic genes expressed (i.e., produce visible results) in all members of a kind.
ALLELES: Genes that can exist in several different forms, e.g., blue vs. brown eyes, hair color, etc. Some are dominant and some recessive. Dominant genes are expressed. Recessive may not be, but can be passed on invisibly from one genera-tion to another and sometimes appear as “throwbacks.”

TYPES OF CELL REPRODUCTIONTYPES OF CELL REPRODUCTION
MITOSIS: The cell makes an exact duplicate of its DNA, then splits into two “daughter” cells that are genetically identical (except in case of a DNA copying mistake, known as a mutation). Most cell reproduction is by mitosis.
MEIOSIS: Two parents each furnish a special reproductive cell with half the kind’s normal amount of DNA to a single-celled offspring. Except in abnormal cases, the offspring receives all the homeotic genes from its parents. It also receives many of the parents’ alleles. After conception, the new organism grows by mitosis.

EFFECTS OF MUTATIONEFFECTS OF MUTATION
ADULT: Unless the mutation occurs in a reproductive cell, it will not be passed on to offspring. In some cases a mutation may produce cancerous growths; in others it may not have an obvious effect.
EARLY STAGES: A mutation in an embryo or infant will be passed on to any cells descended from the affected one. If it is in a homeotic gene it will almost always be harmful or fatal. If it is in an allele of a variable gene it will be recessive and may have no visible effect, but may appear in future generations.

WHAT ENZYMES DOWHAT ENZYMES DO• Enzymes are special
types of protein mol-ecules, made of thousands of amino acids.
• The shapes of the amino acids cause the enzymes to also have a very precise 3-dimensional shape. They are so small that they are able to capture and manipulate individual atoms or molecules.
• Enzymes are able to snap open and
closed because of their 3-D shape. This allows them to either put things together or take them apart.
• They serve as catalysts, speeding up a reaction to millions of times its normal rate.
• Living things use thousands of differ-ent types of en-zymes. Each “kind” has its own unique set of enzymes.

DNA DUPLICATION – The BeginningDNA DUPLICATION – The Beginning
Model of a typical helicase enzyme by D. Fass, C. E. Bogden, J. M. Berger - from the Pro-tein DataBank of RCSB.
Enzymes known as ligases break the hydrogen bonds between A and T, C and G on the two halves of the DNA strand. Next, helicase enzymes exactly matched to the organism’s DNA unwind the halves.
This allows the two com- plementary strands to serve as templates to make two com- plete new DNA molecules.

DNA Error Checking Step 2 – Preliminary ProofreadingDNA Error Checking Step 2 – Preliminary Proofreading• Because of the
matching numbers of hydrogen bonds, “A” and “T” align at a precise distance, as do “C” and “G.”
• If any of the four is accidentally paired with the wrong type, the incorrect distances produce a “bump” on the newly forming DNA strand.
• In a process known as proofreading exo-
nuclease, enzymes move along the strand and check that all distances are correct.
• If they detect a bump, they snip out the offending nucleotide and insert the correct one in its place.
• This brings the rate of copying errors down to about one in 10 million.

DNA Error Checking Step 3 – Final ProofreadingDNA Error Checking Step 3 – Final Proofreading• A family of en-
zymes known as DNA polymerases uses the two halves of a DNA strand to make two copies of the original.
• After the copies are complete, some of the polymerases re-scan them to proofread for errors resulting
from nucleotide mismatches.
• If an error is detected, one of the polymerases snips out the offending segment, then manufactures and inserts a corrected segment.
• This reduces the rate of copying errors to about one in 10 billion.

EVOLUTION: A MATTER OF FAITHEVOLUTION: A MATTER OF FAITHEvolutionists believe that the first living things were
extremely simple. Because DNA had not evolved yet, they must have used some (unknown) far simpler information
storage system. They would not have had any error-correcting mechanisms at all.
• Atheists believe that the elaborate error-correcting mechanisms were later added to DNA one mutation at a time. They must believe that the intricate system of enzymes that prevent errors is itself the result of thousands of perfectly coordinated errors. Errors produced the error prevention mechanism.
• Theists believe that God added the error correcting mechanism much later, then overrode it millions of times because He wanted so much to have evolution.

IS IT SOUP YET? NO!IS IT SOUP YET? NO!Even with a primordial soup containing only Carbon, Hydrogen, Nitrogen, and Oxygen, the chemistry is so complicated that experimenters buy purified amino
acids instead of making their own.But this soup is far too simple!
(1) Two amino acids require Sulfur;
(2) DNA and RNA require Phosphorous;
(3) Early plants would have required Magnesium for photosynthesis; and
(4) Living things also need Iron, Copper, Calcium, and many other elements.
When the extra elements are added to the “soup,” the chemistry to produce a cell becomes impossibly hard.When the extra elements are added to the “soup,” the chemistry to produce a cell becomes impossibly hard.

PARALLEL PLANT AND ANIMAL MUTATIONSPARALLEL PLANT AND ANIMAL MUTATIONS• Many members of the animal kingdom need elements
such as molybdenum, manganese, copper, selenium, iron, calcium, potassium, and so on. They have no way to extract these directly from the environment.
• It just so happens that many plants furnish exactly the minerals that the animals need, in a usable form.
• Since every living thing is supposed to have come from the same single-celled ancestor, there would have had to be two complementary and parallel series of mutations going on for hundreds of millions of years:
2. Plant DNA had to mutate so as to get the minerals out of the ground and make them available to the animals.
Is this an amazing series of millions of coincidences?
Or does it point toward design instead?10-17
1. Animal DNA had to mutate so as to require those specific minerals.

MUTATIONS KNOWN TO HAVE A BENEFITMUTATIONS KNOWN TO HAVE A BENEFIT
BENEFIT TO INDIVIDUAL
1. A certain mutation in a worm known as C. elegans causes it to have more than twice the normal life span.
2. Some birds on the Galapagos islands have inherited a mutation causing them to have small, poorly developed wings. This helps them to be better swimmers.
3. If a person receives the sickle cell trait from just one of his parents, he will be immune to malaria.
Evolution is supposed to happen to species, not individuals. Even these “beneficial” mutations go the wrong way!
HARM TO SPECIES
1. The reproduction rate is greatly reduced, so the species suffers.
2. The birds cannot fly. In any other environment, they could not compete with other species and would probably die off quickly.
3. Malaria is serious but curable. It is not added to the gene pool. Sickle cell is incurable and permanently damages the human gene pool.
A few mutations benefit the individual affected. However, they all harm the affected species.

WHAT IS SICKLE CELL?WHAT IS SICKLE CELL?

Model of sickle-cell hemoglobin by Harrington, Adachi, & Royer – from the Protein DataBank of RCSB.
Site of mutationBecause of the shape of the hemoglobinmolecule, normal blood cells are shapedlike flattened discs. They flow freely through tiny blood ves- sels.
The sickle cell mutation changes the shape of the hemoglobin molecule. Since the blood cell contains millions of these molecules, it as- sumes a sickle shape. This can lead to blockages in small blood vessels.
Sickle cell prevents oxygen from reaching cells. An individual receiving the mutation from both parents will likely die a slow, painful death.
10-19
BENEFIT: If the individual receives the sickle cell trait from only one parent, he or she is immune to malaria.
HARM: sickle cell is permanently added to the gene pool. It does not help the species evolve; it damages it.

HOW CELLS MANUFACTURE PROTEINSHOW CELLS MANUFACTURE PROTEINS1. The cell sends a chemical message (e.g. a hormone) to the DNA in its center
indicating which protein is needed.2. Certain enzymes locate the DNA segment that codes for the needed protein,
then ligases and helicases unzip the two halves of the DNA strand at that location.
3. Other enzymes such as RNA polymerases use one of the strands to put together messenger RNA, which will be used to make the protein.
4. The mRNA is transported to an area of the cell known as endoplasmic reticulum where the manufacturing is done.
5. The mRNA attaches to ribosomes to prepare for the manufacturing to begin.6. Transfer RNA molecules move into place and match up with three
nucleotides on mRNA. Each tRNA molecule (three nucleotides long) matches with exactly one of the 20 amino acids used in living things.
7. As each tRNA molecule puts its attached amino acid in place, the chain of amino acids grows. The tRNA releases the amino acid and goes off to be recycled.
8. When the chain of amino acids is complete, it is carried to another area of the cell where it is folded into its correct 3-dimensional shape.
9. Finally, the complete protein is transported to the area where it is needed.

VIRUSES AND GENE THERAPYVIRUSES AND GENE THERAPYMedical science has learned how to use specific viruses to treat mutated genes. A virus starts out containing a small amount of DNA or RNA. Its normal genetic contents are chemically removed, then a desired unmutated gene is inserted.
If everything goes according to plan, the virus then puts the corrected gene into the patient’s cell.

If everything goes according to plan, the virus then puts the corrected gene into the patient’s cell.
WHY GENE THERAPY IS IRRELEVANT TO EVOLUTION:
1. Gene therapy goes contrary to nature. It is anything but ran-dom. It requires a great deal of intelligent design and careful control to insert specific desired genes into a cell.
2. It is not the virus itself that helps the species, but the artificially inserted gene. Viruses must be carefully selected so as to be effective on the particular species, without harming the subject.
3. The original mutation does not improve anything. The gene therapy is an attempt to undo the mutation by inserting the normal, unmutated gene.

VIRUSES AND BACTERIAVIRUSES AND BACTERIA1. The vast majority of bacteria are not harmful. Their work as
decomposers makes them crucial to life on earth. 2. Only a small number of viruses affect any given species.
Most viruses, too, are not harmful. They are essential to the survival of bacteria. They act like bees pollinating flowers, allowing bacteria to exchange genetic information that helps them to survive in case of a change in their environment.
3. Viruses are insufficient to add billions of nucleotides to DNA.a. Only a few dozen viruses affect any given species, and each
virus only contains one to three genes. Even if a species gained dozens of genes this way and the process repeated hundreds of times, the number of nucleotides added would be a few million, not billions.
b. The process would stop once multi-celled organisms evolved. Viruses are usually not passed on to future generations in sexual reproduction.

Many evolutionists believe that duplicate copies of existing, fully functional genes are occasionally added during reproduction,
then the extra copies mutate to produce new features.
PROBLEMS:
10-28
1. Adding extra copies of genes is usually not beneficial. This is what causes Down, Warkany, Patau, and Edwards syndromes.
2. The duplicate gene contains instructions to perform a specific function. Changing it through mutations causes a loss of genetic information, not a gain.
3. Mutations would have to be responsible for the very first appearance of blood, hearts, lungs, bones, eyes, ears, legs, wings, and every other structure not found in bacteria.
4. Meanwhile, the mutations in the animal kingdom would have made ani-mals need iron, calcium, copper, manganese, molybdenum and many others just as the mutations in the plant kingdom caused plants to go out and get those very minerals out of the soil so animals could use them.

• The machinery sweeps away the carcasses. Only brown ones are left.
• A competitor sneaks in poison, but only white chickens are susceptible. They all die.
• We introduce antibiotics, to which many of them are susceptible. However, a few are immune from the start.
• Since there is no competition, the resistant strain multiplies quickly and fills the ecological niche.
• Even in samples of bacteria frozen for centuries, we always find that some are resistant to any given antibiotic. They’ve always had the resistance.

PLEIOTROPYPLEIOTROPY• Only a small part of DNA contains the coding to
produce proteins. • On the coding sections, it has long been thought that
“one gene -- one protein.” • Experimenters have deliberately induced mutations in
many genes in higher organisms. To their surprise, almost every gene which has been studied in this way affects not just one, but two or more body structures.
• We must conclude that many segments of DNA are used two or more times -- much like the subroutines in a computer program.
DNA contains far more information, encoded in a far more complex way, than we ever realized.

Many species have similar segments of DNA which have no known function. Evolutionists claim that these are “pseudogenes” or “junk DNA” left over
from common ancestors.
THE ATTITUDE: We are SO SMART that if we don’t know the function, there must not be any function.
THE TRUTH: 1. Though we know only a tiny percentage of what happens in DNA, we
have already learned that some segments formerly thought to be useless -- including several “pseudogenes” -- have a definite function after all.
2. Some pseudogenes are thought to be involved in cell differentiation.3. Some have now been found to have a regulatory function, turning other
genes on and off. 4. DNA is a 3-dimensional structure, looping back on itself in many places.
Pseudogenes may contain structural information to help it do so.5. Some segments of DNA contain coding information that is not obvious
because the segments are not continuous. Some pseudogenes may fall into this category.
6. Many pseudogenes may be damaged copies of formerly functional alleles. This is deterioration, NOT evolution.

Not only do similar structures in the adults of different types come from dissimilar genes, they often come from
different body segments in the embryo.
A FEW EXAMPLES:INSECTS: Adult organs that are similar in different species
are produced in “bewilderingly diverse” ways during meta- morphosis. For example, in the larvae of one of the most commoncategories of insects, the beetle (Coeloptera), the foregut and hindgut develop without any cell destruction. However, in butterflies (Lepidoptera), flies (Diptera), ants and bees (Hymenoptera) new structures devel- op only as old ones are replaced. -- R.F. Chapman, The Insects.
PLANT SEEDS: Most biologists consider conifer seeds (pine cones, etc.) homologous to those of angiosperms (flowering plants). However, key parts of the seed such asthe ovule and endosperm form in a way that “profoundly differs in the two groups in a number of important respects.” - M. Denton, Evolution: A Theory in Crisis

Biogeography – The Third Pillar of EvolutionBiogeography – The Third Pillar of Evolution
The same species or genera of animals and plants are sometimes found in different places

Unusual Animals and Plants of the GalapagosUnusual Animals and Plants of the GalapagosThe Galapagos are an isolated chain of islands 600 miles
off the Pacific coast of Ecuador. When Darwin went there as naturalist on H.M.S. Beagle in 1835, he no- ticed many highly specialized groups including
marine iguanas, tortoises, penguins, and finches. He cited these as evidence for evolution.
However, evolutionists believe the islands, which are volcanic, are only a few million years old. Since the genes
for each type of animal would have taken far longer to evolve, each must have come from a founder pop-
ulation which migrated from some- where else.
The Galapagos animals and plants are excellent examples of specialization, but they have nothing to do with the evolution of new types.

THE GALAPAGOS FINCHESTHE GALAPAGOS FINCHESSome have classified Galapagos
finches into 13 different species based on beak shapes. This is incorrect. At least a
few types are able to interbreed. All 13 “species” may be variants
within a single species.
Each beak shape matches well with a specific food source, such as certain types of seeds. If a food type
increases due to weather and other environmental circumstances, finches with matching beaks prosper.
If the food supply diminishes, they tend to die off. When the circumstances return to normal, so do
the percentages of each beak type. There is no evolution going on within
the finch population.

ordered that everyone taller than him be killed. The average height in his country would immediately decrease.
However, as soon as he died or was de- posed, the tall children would no longer be eliminated. Within a few years the average height in his nation would return to its former level.Likewise, the change in average beak size during droughts on the Galapagos islands occurred only because the finches with larger beaks died off. When the droughts ended the large-beak finches began to thrive again and the average beak size returned to its original level.

1. All of us came from Noah’s sons and their wives.
2. Until Babel people were freely inter-breeding so their genes were not sorted out.
There would have been no sharply defined groups. •3. At Babel God decided which people would speak which languages, perhaps according to their genes. From then on they were no longer interbreeding. Clearly defined groups could develop quickly.
4. Natural selection did not cause the group-ing, but would have reinforced it.

highest degree...”
“Reason tells me, that if numerous gradations from a simple and imper-fect eye to one complex and perfect can be shown to exist, each grade being useful to its possessor, as is certain the case; if further, the eye ever varies and the variations be inherited, as is likewise certainly the
case; and if such variations should be useful to any animal under changing conditions of life, then the difficulty of believing that a perfect
and complex eye could be formed by natural selection, should not be considered as subversive of the theory.”

Intelligent Design (I.D.) is a broad concept that allows for the possibility of either direct creation or theistic evolution. Judges nationwide have bought into the
atheistic claim that since the presence of a designer cannot be tested, therefore I.D. is unscientific.
True, we cannot scientifically prove the EXISTENCE of a designer. But the judges have overlooked an ob-
vious question: what sort of scientific test could you perform to prove the NON-EXISTENCE of a designer?

• One piece of the gene that will produce the heavy chain is randomly selected from the 250 segments in cluster 1.
• This is added to one from the 10 in clus-ter 2 plus one of the 6 from cluster 3 and one of the 8 from cluster 4. This gives over 100,000 possible heavy chains.
• The light chain is formed using three segments instead of four, but not neces-sarily the same parts of the segments.

of all types floating around in the bloodstream.
Antibodies are produced in large quantities only when needed. This occurs because some of them stay fastened to the outside
of their cells and send messages to the manufacturing apparatus only when they capture a matching invader. The new mass-
produced antibodies then move freely throughout the body to mark the invaders for destruction.
Not only is the vertebrate system irreducibly complex - there is nothing in invertebrates from which it could have evolved!

VACUOLES AND LYSOSOMESVACUOLES AND LYSOSOMES• Cells often float in a watery environment. Since they contain many
chemicals, the surrounding water tries to equalize the chemical concentration through the process of osmosis. This steadily increases the pressure inside the cell. It would eventually burst and die, except for the presence of safety chambers called vacuoles which periodically release the excess pressure. Vacuoles exist because DNA codes for them.Vacuoles exist because DNA codes for them. There would have been no DNA at the beginning, so early cells would have exploded before they had time to reproduce.
• Once a cell dies, it just wastes space. A multicelled organism would quickly became a bag of garbage, except that tiny “suicide sacs” called lysosomes rupture at death, releasing enzymes which digest the dead cell from the inside out and allow its remnants to be flushed out or recycled. Lysosomes, too, are present because DNA codes for them. Lysosomes, too, are present because DNA codes for them. Since there would have been no DNA at the beginning, life would have quickly drowned in garbage.

CAMOUFLAGECAMOUFLAGEMany animals (Walking Sticks, Leafhoppers, Oyster Fish, et al.) blend in with their surroundings, because they look like the surroundings. They blend perfectly with their environment not because they need camouflage but because it is programmed into their DNA. This is hard enough to explain when they look like inanimate objects such as rocks, but even harder when many of them look like surrounding plants whose features are also determined by their DNA. Either the two kinds of DNA evolved independently and just “happen” to fit together or else they were designed that way.

Active Transport in PlantsActive Transport in PlantsNature tends toward equilibrium, e.g., energy flows from greater to lesser concentration (2nd Law of Thermodynamics), water flows across a membrane in osmosis to try to equalize the concentration of chemicals, etc. Plants do exactly the opposite. Their roots contain enzymes that allow them to seek out specific elements (iron, manganese, etc.) from thesurrounding soil, allowing them to reach up to 10,000 times as high a concentration of those elements as the soil. This is exactly the opposite of what nat- ural processes produce. It only happens because the plant’s DNA contains the coding to produce those specific enzymes.

open ocean with no landmarks. If their navigation were off by a tenth of a degree, they would fall into the ocean and drown.

Until the birds’ migratory sense evolved to match the moving continents, they would have fallen into the ocean and drowned!

Sap Transport in Tall TreesSap Transport in Tall Trees
10-78
Water goes up a straw not because of suction, but because of atmospheric pressure.
The highest column of water the atmo- sphere can support is about 32 feet. This means that natural processes would limit trees to about 32 feet tall - yet some grow to over a hundred feet. How does the water get to the top? Rather than rely on atmospheric pressure, tall trees have built-in pumps! The pumps arepresent because the tree’s DNA codes for them, not because natural selection forces them to evolve.
Nature goes exactly the opposite way!

WHO NEEDS FACTS WHEN YOU CAN MAKE UP STORIES?WHO NEEDS FACTS WHEN YOU CAN MAKE UP STORIES?Darwin said, “To suppose that the eye with all its inimitable contrivances for adjusting the focus to different distances, for admitting different amounts of light, and for the correction of Spherical and chromatic aberration, could have been formed by natural selection, seems, I freely confess, absurd in the
highest degree...”
“Reason tells me, that if numerous gradations from a simple and imper-fect eye to one complex and perfect can be shown to exist, each grade being useful to its possessor, as is certain the case; if further, the eye ever varies and the variations be inherited, as is likewise certainly the
case; and if such variations should be useful to any animal under changing conditions of life, then the difficulty of believing that a perfect
and complex eye could be formed by natural selection, should not be considered as subversive of the theory.”

CLEANING SYMBIOSISCLEANING SYMBIOSISWhen certain species of small birds, fish, or shrimp walk or swim up to certain vicious types of predators (crocodiles,sharks, barracudas, etc.), the predator opens its mouth and allows them to enter, pick off debris, and leave safely. Any other species get eaten.
If this behavior is the result of mutations, then multiple species of cleaners must have acquired mutations making them want to enter a predator’s mouth at the same time those predators acquiredmutations that made them decide not to eat the cleaners.
It sure is lucky for the cleaners that the predators’ mutations happened at the same time!

IS INTELLIGENT DESIGN UNSCIENTIFIC?IS INTELLIGENT DESIGN UNSCIENTIFIC?Intelligent Design (I.D.) is a broad concept that allows for the possibility of either direct creation or theistic evolution. Judges nationwide have bought into the
atheistic claim that since the presence of a designer cannot be tested, therefore I.D. is unscientific.
True, we cannot scientifically prove the existence of a designer. But the judges have overlooked an
obvious question: what sort of scientific test could you perform to prove there is NOT a designer?
In what way is teaching the IMPOSSIBILITY of intel-ligent design any more scientific than teaching the
