Cytosine numbering
WebDec 9, 2024 · The chemical formula of the pyrimidine cytosine is C 4 H 5 N 3 O. Its symbol is C. This base is found in both DNA and RNA. Cytidine triphosphate (CTP) is an enzyme cofactor that can convert ADP to ATP. … WebCytosine 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).
