It is one of the four main bases found in DNA and RNA, along with adenine, guanine, and thymine (uracil in RNA). It is a pyrimidine derivative, with a heterocyclic aromatic ring and two substituents attached. The nucleoside of cytosine is cytidine. In Watson-Crick base pairing, it forms three…

It is a nucleoside molecule that is formed when cytosine is attached to a ribose ring (also known as a ribofuranose) . Cytidine is a component of RNA.If cytosine is attached to a deoxyribose ring, it is known as a deoxycytidine.Dietary sources of cytidine include foods with high RNA (ribonucleic…
