Genes carry information essential for producing all the proteins required by all organisms.
These proteins determine, among other things, how the organism looks, how well its body metabolizes food or fights infection, and sometimes even how it behaves. The human genome, for example, has 3 billion pairs of bases. Ts, Cs, and Gs is extremely important. Because all organisms are related through similarities in DNA sequences, insights gained from nonhuman genomes often lead to new knowledge about human biology. The human genome is made up of DNA, which has four different chemical building blocks.
