Genetic types
There are four types of bases: adenine (A), cytosine (C), guanine (G), and thymine (T). The phosphates make hydrogen bonds with the sugars to make long phosphate-sugar backbones. Bases specifically pair together (T&A, C&G) between two backbones and make like rungs on a ladder. See more Genetics is the study of genes, genetic variation, and heredity in organisms.
