is uracil a pyrimidine

The name "uracil" was coined in 1885 by the German chemist Robert Behrend, who was attempting to synthesize derivatives of uric acid. Uracil is produced by hydrolysis of nucleic acid and used in biochemical research. 5-Fluorouracil enters the biosynthetic chain but forms an inactive complex which blocks the synthesis of pyrimidine nucleotides and hence inhibits DNA synthesis in cancer cells.

Uracil is therefore structurally analogous to thymine in molecules of DNA. Adenine and guanine are purine bases while cytosine, thymine and uracil are pyrimidine bases.
PUPYU : Purines (adenine, guanine, xanthine, hypoxanthine) and pyrimidines (uracil, thymine, cytosine, orotic acid) are involved in all biological processes, providing the basis for storage, transcription, and translation of genetic information as RNA and DNA. Purines are the heterocyclic organic compounds which have pyrimidines ring in them. Answer. Cloudflare Ray ID: 606db83a2ac50ce5 Purines make up two of the four nucleobases in DNA and RNA: adenine and guanine.
