The genes are coded in deoxyribonucleic acid (DNA), helical double-stranded molecules folded into chromosomes in the nucleus of cells. The Human Genome Project was created several years ago to sequence the human genome. This national effort has generated information on the role of genetics in congenital defects, cancer, disorders involving the immune system, and other diseases that have a genetic link.
