Cytosine base

WebApr 8, 2024 · Along with adenine, guanine, and thymine, cytosine is one of the four major bases present in DNA and RNA (uracil in RNA). It's a pyrimidine derivative with two substituents and a heterocyclic aromatic ring (an amine group at position 4 and a keto group at position 2). Cytidine is the nucleoside of cytosine. Webcytosine: [noun] a pyrimidine base C4H5N3O that codes genetic information in the polynucleotide chain of DNA or RNA — compare adenine, guanine, thymine, uracil.
