Pyrimidine (C4H4N2; /pɪˈrɪ.mɪˌdiːn, paɪˈrɪ.mɪˌdiːn/) is an aromatic, heterocyclic, organic compound similar to pyridine (C5H5N). One of the three diazines...

Pyrimidine dimers represent molecular lesions originating from thymine or cytosine bases within DNA, resulting from photochemical reactions. These lesions...

Pyrimidine biosynthesis occurs both in the body and through organic synthesis. De Novo biosynthesis of a pyrimidine is catalyzed by three gene products...

The purine bases adenine and guanine and pyrimidine base cytosine occur in both DNA and RNA, while the pyrimidine bases thymine (in DNA) and uracil (in RNA)...

of cytosine, uracil, and thymine is derived of pyrimidine, so those three bases are called the pyrimidine bases. Each of the base pairs in a typical double-helix...

Pyrimidine analogues are antimetabolites which mimic the structure of metabolic pyrimidines. Nucleobase analogues Fluorouracil (5FU), which inhibits thymidylate...

demethylated form of thymine. Uracil is a common and naturally occurring pyrimidine derivative. The name "uracil" was coined in 1885 by the German chemist...

nitrogenous base. The bases found in nucleic acids are either purines or pyrimidines. In the more complex multicellular animals, they are both primarily produced...

In enzymology, a pyrimidine-5'-nucleotide nucleosidase (EC 3.2.2.10) is an enzyme that catalyzes the chemical reaction a pyrimidine 5'-nucleotide + H2O...

a heterocyclic aromatic organic compound that consists of two rings (pyrimidine and imidazole) fused together. It is water-soluble. Purine also gives...
