Watson-Crick base pairs is a specific complementary base pairs that base A is always paired with base T while base G is always paired with base C. These base pairs were introduced by James Watson and Francis Crick. In Watson-Crick base pairs, the number of hydrogen bonds formed between A and T are 2 while there are 3 formed between base G and C. [1] Cytosine and Thymine are pyrimidine compounds and Guanine and Adenine are purine compounds. The purine compunds are larger than the pyrimidines as the 6-membered ring has an extra 5-membered ring fused to it. [2]
