A Brief Guide to Genomics
An organism's complete set of DNA is called its genome.
Virtually every single cell in the body contains a complete copy
of the approximately 3 billion DNA base pairs, or letters, that make up the human genome.
With its four-letter language, DNA contains the information needed to build the entire
human body. A gene traditionally refers to the unit of DNA that carries the instructions for
making a specific protein or set of proteins. Each of the estimated 20,000 to 25,000 genes in
the human genome codes for an average of three proteins.
Located on 23 pairs of chromosomes packed into the nucleus of a human cell, genes direct
the production of proteins. If a cell's DNA is mutated, an abnormal protein may be produced,
which can disrupt the body's usual processes and lead to a disease, such as cancer.
The Human Genome Project
The Human Genome Project, which was led at the National Institutes of Health, produced a
very high-quality version of the human genome sequence completed in April 2003, all 23
chromosome’s genes have been located and identified like the one attached.
The Human Genome Project was designed to generate a resource that could be used for a
broad range of biomedical studies. One such use is to look for the genetic variations that
increase risk of specific diseases, such heart disease, diabetes, blindness, and cancer.
Genome-based research is already enabling medical researchers to develop more effective
diagnostic tools, to better understand the health needs of people based on their individual
genetic make-ups, and to design new treatments for disease.
