Genetics, the branch of biology that deals with heredity, incorporates the chemistry of complex-but-understandable substances that include DNA and RNA. Component parts of these chemicals of life include four organic bases—two classed among the purines and two among the pyrimidines. These bases work in pairs, weakly united by hydrogen bonds. The four bases, adenine, cytosine, guanine, and adenine are found in various life forms, from man to cow. Persons employed in such genetics research are called cytogeneticists. Gain insight into the functionality of the bases and how they work to determine heredity, by considering intelligently written articles by your Bright Hub contributors.
