Uracil - Wikipedia
Uracil (/ ˈjʊərəsɪl /) (symbol U or Ura) is one of the four nucleotide bases in the nucleic acid RNA. The others are adenine (A), cytosine (C), and guanine (G). In RNA, uracil binds to adenine via two hydrogen bonds. In DNA, the uracil nucleobase is replaced by thymine (T). Uracil is a demethylated form of thymine.

Uracil | C4H4N2O2 | CID 1174 - PubChem
Uracil is a common and naturally occurring pyrimidine nucleobase in which the pyrimidine ring is substituted with two oxo groups at positions 2 and 4. Found in RNA, it base pairs with adenine and replaces thymine during DNA transcription.
Why Uracil is Only Present in RNA? - GeeksforGeeks
2023年4月27日 · Uracil is one of the four nitrogenous bases present in RNA, the other three being adenine, guanine, and cytosine. Unlike DNA, RNA contains uracil in place of thymine. This difference between DNA and RNA is important as it affects their properties and functions.
