Cytosine consists of a heterocyclic aromatic ring, an amine group at C4, and a keto group at C2. Cytosine binds with ribose to form the nucleoside cytidine and with deoxyribose to form deoxycytidine. The molecule is of planar geometry and cytosine forms 3 hydrogen bonds with Guanine in the DNA double helix.
Cytosine (C) is one of the four main bases found in DNA and RNA, along with adenine, guanine, and thymine (uracil in RNA).
Cytosine is a pyrimidine, which forms three hydrogen bonds to base pair with guanine. It forms a nucleotide cytidine, that is phosphorylated to cytidine 5′ monophosphate (CMP), cytidine 5′ diphosphate (CDP) and cytidine 5′ triphosphate (CTP).
