Step 1I'll solve this problem step by step, focusing on the differences between purines and pyrimidines:
Step 2: Definition of Purines and Pyrimidines
Purines and pyrimidines are two types of nitrogenous bases found in nucleic acids (DNA and RNA). They differ in their chemical structure and molecular size: - Purines: Larger, double-ring structures - Pyrimidines: Smaller, single-ring structures
Final Answer
Purines (A, G) are larger, double-ring bases that always bond with smaller, single-ring pyrimidines (T/U, C) in a complementary base pairing pattern specific to DNA and RNA.
