BIOMOLECULES AND ENZYMES

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: -Cytosine, thymine, and uracil are all pyrimidines.

Detailed explanation-4: -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.

Detailed explanation-5: -One of two chemical compounds that cells use to make the building blocks of DNA and RNA. Examples of pyrimidines are cytosine, thymine, and uracil. Cytosine and thymine are used to make DNA and cytosine and uracil are used to make RNA.
