Explanation:
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: -There are two hydrogen bonds holding the two nitrogenous bases together. One of the hydrogen bonds is formed between one of the Hydrogen atoms of the amino group at C-6 of adenine and the Oxygen atom of the keto group at C-4 of thymine.
Detailed explanation-3: -The two strands are held together by hydrogen bonds between pairs of bases: adenine pairs with thymine, and cytosine pairs with guanine.
Detailed explanation-4: -There are two hydrogen bonds between A and T while three hydrogen bonds between Guanine (G) and Cytosine (C).
