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 pyrimidine deoxynucleoside.It is the DNA nucleoside T, which pairs with deoxyadenosine (A) in double-stranded DNA.It can be phosphorylated with one, two or three phosphoric acid groups, creating respectively deoxythymidine mono,di or triphosphate.It is non-toxic and as part of one of the…
