WebA nucleotide is made up of a sugar (deoxyribose), a phosphate group, and one of four nitrogenous bases: adenine (A), thymine (T), guanine (G) or cytosine (C). C and T bases, which have just one ring, are called pyrimidines, while A and G bases, which have two rings, are called purines. Webkinase, an enzyme that adds phosphate groups (PO 43−) to other molecules. A large number of kinases exist—the human genome contains at least 500 kinase-encoding genes. Included among these enzymes’ targets for phosphate group addition ( phosphorylation) are proteins, lipids, and nucleic acids.
