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 is an aminopyrimidine that is pyrimidin-2-one having the amino group located at position 4. It has a role as a human metabolite, an Escherichia coli metabolite, a Saccharomyces cerevisiae metabolite and a mouse metabolite.

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.

1 day ago · 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.

Nov 8, 2018 · The molecular formula of cytosine is C 4 H 5 N 3 O. 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.

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 ...

Aug 27, 2021 · 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 ...

May 21, 2024 · Cytosine is one of five nitrogenous bases that are attached to a five carbon sugar, pentose, and a phosphate group to make nucleotides. Nucleotides are the units that join together to make DNA and RNA molecules.

C4H5N3O is the molecular formula for cytosine. A heterocyclic aromatic ring, an amine group at C-4, and a keto group at C-2 make up cytosine. Cytosine forms the nucleoside cytidine when it binds to ribose, and deoxyribose forms deoxycytidine when it binds to deoxyribose.

Cytosine is one of the 5 main nitrogenous bases used in storing and transporting genetic information within a cell. 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).
