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: -Adenine (A) and guanine (G) are purines, and cytosine (C), thymine (T), and uracil (U) are pyrimidines.
Detailed explanation-3: -Pyrimidines consist of single ringed structure and examples are cytosine, uracil and thymine.
Detailed explanation-4: -Cytosine, thymine, and uracil are all pyrimidines.
Detailed explanation-5: -Hydrogen bonding and base stacking interactions of pyrimidines are important for stabilizing the three-dimensional structure in nucleic acids. The most important biological substituted pyrimidines are cytosine, thymine, and uracil.
