Detailed explanation-1: -Uracil is pyrimidine base. Pyrimidine is an aromatic heterocyclic organic compound similar to pyridine. Three types of nucleobases are pyrimidine derivatives: cytosine(C), thymine(T), and uracil(U).
Detailed explanation-2: -Pyrimidine: A nitrogenous base similar to benzene (a six-membered ring) and includes cytosine, thymine, and uracil as bases used for DNA or RNA.
Detailed explanation-3: -The pyrimidine bases are thymine (5-methyl-2, 4-dioxipyrimidine), cytosine (2-oxo-4-aminopyrimidine), and uracil (2, 4-dioxoypyrimidine) (Fig. 6.2).
Detailed explanation-4: -Cytosine, thymine, and uracil are all pyrimidines.
Detailed explanation-5: -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.
