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 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.

4 天之前 · 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.

2024年12月13日 · Uracil, with its distinct structure and role in RNA, is a vital component of molecular biology. Its ability to form stable base pairs with adenine and interact with enzymes makes it an essential player in the complex world of nucleic acids. Understanding the structure and function of Uracil provides insights into the fundamental processes of ...

2021年1月19日 · Uracil, similar to other pyrimidines, is formed from a series of steps, beginning with the formation of carbamoyl phosphate. Carbamoyl phosphate forms from a reaction involving bicarbonate, glutamine, ATP, and water molecule.

Uracil is used in animals and plants to help carry out the synthesis of many enzymes necessary for cell function through bonding with riboses and phosphates (Garrett and Grisham). Uracil serves as an allosteric regulator and coenzyme for reactions in …

Uracil is one of the most notable pharmacophores in medicinal chemistry as the pyrimidine nucleobase forms an integral part of many commercial drugs. Though the name uracil is usually associated with cancer drugs, there are many uracil-based compounds which can.

Uracil is a pyrimidine nucleobase that is found only in RNAs. It is denoted by U or Ura. It is a demethylated form of thymine that forms hydrogen bonds with adenine in a RNA polynucleotide chain.

Uracil is a pyrimidine nucleobase that is widely used in medicinal chemistry for the treatment of various diseases, including viral infections, cancer, diabetic, thyroid, and autosomal recessive disorders.
