Excerpt. © Reprinted by permission. All rights reserved.:
A gene is a series of DNA nucleotides that codes for the production of a single polypeptide or RNA. Eukaryotes have more than one copy of some genes, called repetitive sequence DNA, while prokaryotes have only one copy of each gene, called unique-sequence DNA. Even in eukaryotes, unique-sequence DNA dominates. Unique sequence DNA usually codes for proteins, while moderately repetitive DNA sequences code for some proteins but mostly rRNA and tRNA. Highly repetitive DNA sequences appear to be associated with noncoding DNA called heterochromatin.
There are between 26,000 and 38,000 genes in the human genome. The entire DNA sequence of an organism is called the genome. Only a little over 1% of a human genome actually codes for protein. Variation of the nucleotide sequence among humans is small; human DNA differs from individual to individual at approximately 1 nucleotide out of every 1200 or about 0.08%. The variation between humans and chimpanzees is about 2%.
The Central Dogma of gene expression is that DNA is transcribed to RNA, which is translated to amino acids forming a protein. All organisms use this same method to express their genes.
