Description and Uses

Cytosine is pyrimidine; along with adenine and guanine they account for the fi ve nucleic acid bases. Pyrimidines are heterocyclic single-ringed compounds based on the structure of pyrimidine. Cytosinelike adenine and guanine, form nucleosides and nucleotides in RNA and DNA. When the bases combine with ribose, a ribonucleoside forms; and when it attaches to deoxyribose, a deoxyribosenucleoside is formed. Names of the nucleoside are summarized in Table 29.1.these in turn combine with phosphoryl groups, in a process called phosphorylation, to form their respective nucleotides that form nucleic acids.the nucleotides can be tri, di, and mono phosphate nucleotides similar to the way in which adenine forms ATP, ADP, and AMP.

Widely distributed in nature; constituent of nucleic acids
