Detailed explanation-1: -The bases are the “letters” that spell out the genetic code. In DNA, the code letters are A, T, G, and C, which stand for the chemicals adenine, thymine, guanine, and cytosine, respectively. In base pairing, adenine always pairs with thymine, and guanine always pairs with cytosine.
Detailed explanation-2: -The chemical structures of Thymine and Cytosine are smaller, while those of Adenine and Guanine are larger. Size and structure of the specific nucleotides cause Adenine and Thymine to always pair together while Cytosine and Guanine always pair together.
Detailed explanation-3: -In DNA, adenine always pairs with thymine (A-T), and guanine always pairs with cytosine (G-C).
Detailed explanation-4: -These nitrogenous bases do not have a perfect match between hydroge.
