Module 7

Cellular Reproduction andDNA

Genetics What characteristics of your

parents do you share? Do you look a lot like one parent or

the other OR do you look like another relative?

What about your siblings? Do you look alike or not? What characteristics do you share?

Genetics How can a set of brown-eyed, brown

haired parents have a child with blue eyes and blond hair?

What do you think about parents who have conducted in strength training or strenuous activities producing a strong child?

Discuss - Genetics vs. God Given Temperament

Genetics Define Genetics The science that studies HOW

characteristics get passed from parent to offspring

Define Temperament The God given makeup of YOU –

most people call it personality (but there is a difference)

Genetics

Most of your “traits” and “characteristics” are governed by what kinds of proteins your cells make

Eye color – dependent on what proteins are produced in some of the cells in your eyes – the special coding

Your DNA determines your eye color

Genetics

What is DNA? Deoxyribonucleic Acid Let’s watch a short video clip on

DNA http://

Let’s Discuss Where in the cell is DNA found? In the cell’s nucleus Is everyone’s DNA different? Yes! How is DNA arranged in your body? In a spiral shape called a

Double Helix with long strands called Chromosomes

DNA What are the four

chemicals that pair up with one another in a DNA strand?

DNA

Their pair up ONLY in this format: Adenine with Thymine – remember

“AT” Guanine with Cytosine

DNA

What are your thoughts on cloning people and/or animals?

With a partner discuss the pros and cons of genetically modified plants (5 minutes), then we’ll discuss

DNA How has the use of DNA helped us

today? Diseases or malformations

Cures or treatments for certain diseases Amniocentesis on babies

Debunk evolutionists that we were created on purpose by our Creator and not evolved

Paternity tests Forensic Science and Crime Scene

Investigation – innocent or guilty??

Interesting DNA Trivia Human DNA contains about 3 billion base pairs

arranged into 46 chromosomes Humans and E coli bacteria share about 7

percent of the same DNA A significant percent of DNA has no known

function (so far as we know it…). Scientists call it “junk DNA” and may play a roll we just don’t understand yet

Every minute, your body produces enough DNA that if the strands were stacked end to end, they’d be 100,000 kilometers long (60,000 miles)

The genetic difference between two unrelated people is about 0.2% of their DNA

DNA DNA is NOT the only factor in

determining what kind of person you will be

Scientifically, there are three factors in determining the characteristics of a person: Genetic Factors Environmental Factors Spiritual Factors

Genetic Factor

The general guideline of traits determined by a person’s DNA

Environmental Factor

Those “nonbiological” factors that are involved in a person’s surroundings such as the nature of the person’s parents, the person’s friends, and the person’s behavioral choices

I call this character and personality

Spiritual Factor

The factors in a person’s life that are determined by the quality of his or her relationship with God

Let’s Compare Factors with Temperament Temperament has

three basic building blocks

Personality or Self-Selected Mask

Learned Behavior or Character

God given Temperament

Genes

The information for an organism’s DNA is split up into little groups known as genes

Gene – a section of DNA that codes for the production of a protein or a portion of protein, thereby causing a trait

Question

Two identical twins have exactly the same set of genes. They are separated at birth and grow up in different households. If a scientist were to study the twins as adults, would be find them to be identical in every way, since they have the same genes? Why or why not?
