Genes are made up of DNA. Each chromosome contains many genes. A gene is the basic physical and functional unit of heredity. Genes, which are made up of DNA, act as instructions to make molecules called proteins. In humans, genes vary in size from a few hundred DNA bases to more than 2 million bases.
A single gene may contain thousands of bases, so the Human Genome Project (HGP) is not any easy task. First, scientists have to go into the cells nucleus, where the DNA is located. Here the DNA is tightly coiled, so researchers have to uncoil it and then examine the DNA and write down the order of the bases.
