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: -Two hydrogen bonds form between adenine and thymine or adenine and uracil. Complementary pairs always involve one purine and one pyrimidine base *.
Detailed explanation-3: -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-4: -Adenine-uracil base pairs, or AU base pairs, are held together by 2 hydrogen bonds. Guanine-cytosine base pairs, or GC base pairs, are held together by 3 hydrogen bonds.
Detailed explanation-5: -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. Figure 22.2.
