Human Genome The sum total of DNA in an organism is its

genome.

The Human Genome Project (HGP) an international effort, began in October 1990, and was completed in 1999, 2003, 2004. (http://www.pbs.org/wgbh/nova/genome/program.html)

Project goals were to: Determine the complete sequence of the 3

billion DNA bases Identify all human genes And make them accessible for further

biological study

6

Human Genome

The bacterium E. coli and others were used to help develop the technology and interpret human gene function.

The Human Genome Project was sponsored by:

The U.S. Department of Energy and The U.S. National Institutes of Health

DNA (ACGT)

Humans have from 10 to 100 trillion cells

Each Human cell has about 3 billion nucleotides

We have approximately 30,000 genes

Of the three billion letters of DNA that we have,

only 1 to 1.5 percent of it is gene the rest is STUFF”.

The functions are unknown for over 50% of known genes

DNA (ACGT)

Human Genome

3,000,000,000 ~ dna bases 30,000,000 ~ bases in genes 2,970,000,000 ~ stuff

adenine (A) forms a base pair with thymine (T) guanine (G) forms a base pair with cytosine (C)

Similarities to Human DNA Another

human? 99.9% - All humans have the same genes, but some of these genes contain sequence differences that make each person unique.

A chimpanzee? 98.5% - Chimpanzees are the closest living species to humans.

A mouse? 92.0% - All mammals are quite similar genetically.

A fruit fly? 44.0% - Studies of fruit flies have shown how shared genes govern the growth and structure of both insects and mammals.

Yeast? 26.0% - Yeasts are single-celled organisms, but they have many housekeeping genes that are the same as the genes in humans, such as those that enable energy to be derived from the breakdown of sugars.

A weed (thale cress)?

18.0% - Plants have many metabolic differences from humans. For example, they use sunlight to convert carbon dioxide gas to sugars. But they also have similarities in their housekeeping genes.

10

The gene sizes Largest known human gene is dystrophin at 2.4 million bases.

Chromosome 21 is the smallest human chromosome. Three copies of this autosome causes Down syndrome, the most frequent genetic disorder associated with significant mental retardation.

Academic groups from Germany and Japan mapped and sequenced it, it has 33,546,361 bp of DNA

Analysis of the chromosome revealed: 127 known genes, 98 predicted genes, and 59 pseudogenes.

Smallest bacterial genome, Mycoplasma genitalium size of 580 kbp

Proteins: Structures Chemical properties that distinguish the 20 different

amino acids cause the protein chains to fold up into specific three-dimensional structures that define their particular functions in the cell

18

Reality Somewhere in this dense chemical forest

are genes involved in deafness, Alzheimer, cancer, cataracts, etc.

But where? This is such a maze scientists need a map.

Out of three billion base pairs in our DNA, just one single letter can make a difference.
