A nucleotide is made of a phosphate, a molecule of ribose or 2'-deoxyribose, and another molecule called a nitrogenous base. The initial letters of the base names that spell out the genetic code. A, T, G, and C stand for the chemicals adenine, thymine, guanine, and cytosine, respectively. In base pairing, adenine always pairs with thymine, and guanine always pairs with cytosine.
