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 - National Human Genome Research Institute
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 | 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 Definition and Examples - Biology Online Dictionary
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.
Keeping Uracil Out of DNA: Physiological Role, Structure and ...
To prevent uracil incorporation into DNA, representatives of the dUTP nudeotidohydrolase (dUTPase) enzyme family eliminate excess dUTP. This Account describes recent studies that have provided important detailed insights into the structure and function of these essential enzymes.
11.1: Structure and Function - Nucleic Acids - Biology LibreTexts
The nitrogenous bases found in nucleic acids include adenine and guanine (called purines) and cytosine, uracil, or thymine (called pyrimidines). There are two sugars found in nucleotides - deoxyribose and ribose (Figure 2.128).
Uracil: A Pharmacophore with Diverse Biological Potential
This review article delves into the intricate biological activities of uracil, an essential pyrimidine Base pivotal in RNA structures. Examining its involvement in nucleic acid metabolism, various multifunctional roles, spanning from influencing cell proliferation to its antimicrobial and antiviral properties.
Uracil Definition & Meaning - Merriam-Webster
The meaning of URACIL is a pyrimidine base C4H4N2O2 that is one of the four bases coding genetic information in the polynucleotide chain of RNA.
Uracil in DNA – occurrence, consequences and repair
Uracil in DNA results from deamination of cytosine, resulting in mutagenic U : G mispairs, and misincorporation of dUMP, which gives a less harmful U : A pair.
