Uracil - Wikipedia
Uracil (/ ˈ j ʊər ə s ɪ l /) (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 .

uracil, a colourless, crystalline organic compound of the pyrimidine family that occurs as a component of ribonucleic acid (RNA), a molecule involved in the transmission of hereditary characteristics.

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.

Uracil - National Human Genome Research Institute
Definition. Uracil (U) is one of the four nucleotide bases in RNA, with the other three being adenine (A), cytosine (C) and guanine (G). In RNA, uracil pairs with adenine. In a DNA molecule, the nucleotide thymine (T) is used in place of uracil.

Uracil Definition and Examples - Biology Online Dictionary
Uracil has a molar mass of 112.08676 g/mol and a melting point of 335 °C. It may occur as a component of a nucleoside (nucleobase + sugar deoxyribose or ribose) or of a nucleotide (nucleoside with phosphate groups). It is also one of the five primary (canonical) nucleobases in nucleic acids.
