Not to be confused with uridine. 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.
19 Ιαν 2021 · Uracil is a pyrimidine nucleobase with a chemical formula of C 4 H 4 N 2 O 2. Pyrimidine is a heterocyclic aromatic organic compound with a single ring (called a pyrimidine ring) with alternating carbon and nitrogen atoms. Uracil has a molar mass of 112.08676 g/mol and a melting point of 335 °C.
6 ημέρες πριν · 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, 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. The RNA molecule consists of a sequence of nucleotides, each containing a five-carbon sugar.
The structure of uracil consists of a six-membered ring containing two nitrogen atoms, and its chemical formula is C4H4N2O2. Uracil is involved in the regulation of gene expression through its role in mRNA and its participation in RNA splicing.
Uracil is a key nucleobase in RNA, forming base pairs with adenine. It plays crucial roles in RNA structure, function, and the genetic code, with applications in biotechnology.
A nucleotide consists of a sugar molecule (either ribose in RNA or deoxyribose in DNA) attached to a phosphate group and a nitrogen-containing base. The bases used in DNA are adenine (A), cytosine (C), guanine (G) and thymine (T). In RNA, the base uracil (U) takes the place of thymine.
