Cytosine - Wikipedia
Cytosine (/ ˈ s aɪ t ə ˌ s iː n,-ˌ z iː n,-ˌ s ɪ n / [2] [3]) (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 ...
Cytosine | base, nucleobase, DNA | Britannica
Cytosine, a nitrogenous base derived from pyrimidine that occurs in nucleic acids, the heredity-controlling components of all living cells, and in some coenzymes, substances that act in conjunction with enzymes in chemical reactions in the body.
Cytosine - National Human Genome Research Institute
2024年12月29日 · 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.

2021年8月27日 · Cytosine is a pyrimidine nucleobase with a chemical formula of C 4 H 5 N 3 O. Pyrimidine is a heterocyclic aromatic organic compound with a single ring (called a pyrimidine ring) with alternating carbon and nitrogen atoms. Cytosine has a molar mass of 111.10 g/mol and a melting point of 320 to 325 °C. It can occur in nucleic acids, such as DNA ...
Cytosine in DNA and RNA: Functions, Modifications, and
Cytosine is one of the four main nitrogenous bases found in DNA and RNA, along with adenine (A), guanine (G), and thymine (T) or uracil (U). It is a pyrimidine derivative, meaning it has a single-ring structure. In the DNA double helix, cytosine forms a base pair with guanine via three hydrogen bonds, contributing to the stability of the DNA ...
