cytosine
n 1: a base found in DNA and RNA and derived from pyrimidine;
pairs with guanine [synonym: {cytosine}, {C}]

The Collaborative International Dictionary of English v.0.48 (gcide)

cytosine \cy"to*sine\ (s[imac]"t[-o]*s[i^]n or
s[imac]"t[-o]*s[=e]n), n. (Biochemistry)
A pyrimidine ({C4H5N3O}) which is one of the four major basic
components of DNA and RNA in most organisms, forming
glyosides with ribose and deoxyribose. It is the basic
component of cytidine, deoxycytidine, cytosine, cytidine
monophosphate, and derivatives of those compounds.

Cytosine - Wikipedia
Cytosine[a] (symbol C or Cyt) is one of the four nucleotide 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 (an amine group at position 4 and a keto group at position 2) The nucleoside of cytosine is cytidine In Watson–Crick base pairing, it forms three
Cytosine - National Human Genome Research Institute
Cytosine (C) is one of the four nucleotide bases in DNA, with the other three being adenine (A), guanine (G) and thymine (T) Within a double-stranded DNA molecule, cytosine bases on one strand pair with guanine bases on the opposite strand The sequence of the four nucleotide bases encodes DNA’s information
