Cytosine biosynthesis
WebCytosine is a pyrimidine-type nitrogenous base, which serves for the biosynthesis of cytidine-5'-monophosphate and deoxycytidine-5'-monophosphate. These compounds serve for the biosynthesis, respectively, of deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). DNA stores genetic information and RNA has various functions.
