Detailed explanation-1: -The Adenine-Thymine base pair is held together by 2 hydrogen bonds while the Guanine-Cytosine base pair is held together by 3 hydrogen bonds.
Detailed explanation-2: -It is a truth universally acknowledged that a guanine–cytosine (GC) base pair has three hydrogen bonds whereas adenine–thymine (AT) has two.
Detailed explanation-3: -The base pairs are stabilized by hydrogen bonds; adenine and thymine form two hydrogen bonds between them, whereas cytosine and guanine form three hydrogen bonds between them.
Detailed explanation-4: -Purines always bond with pyrimidines via hydrogen bonds following the Chargaff rule in dsDNA, more specifically each bond follows Watson-Crick base pairing rules. Therefore adenine specifically bonds to thymine forming two hydrogen bonds, whereas guanine forms three hydrogen bonds with Cytosine.
