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 | Nucleobase, Nucleoside & DNA | Britannica
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
5 days ago · 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
Jan 19, 2021 · 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.
Structural Biochemistry/Nucleic Acid/Nitrogenous Bases/Pyrimidines/Uracil
Uracil is among the five nucleobases: adenine, guanine, cytosine, and thymine,but is only found in RNA. It is a naturally occurring pyrimidine derivative with the molecular formula C 4 H 4 N 2 O 2. Uracil is planar and unsaturated and has the ability to absorb light.

The Importance of the Fifth Nucleotide in DNA: Uracil
Feb 24, 2023 · Uracil is a base analogue of thymine and is found in both DNA and RNA (Figure 1). As a pyrimidine nucleotide it has an amino acid group at the 2′ position and a carboxy group at the 5′ position. U and T are equivalent in their information storage, transmission and their base pairing with adenine.
