Hydrogen bonding is strongest between
A) adenine and guanine.
B) uracil and thymine.
C) guanine and uracil.
D) adenine and thymine.
E) cytocine and guanine.

Question

Quizplus · Accepted Answer

Hydrogen bonding between nucleotides in DNA is responsible for base pairing, which is specific and crucial for DNA replication and protein synthesis. The proper base pairing involves hydrogen bonding between cytosine (C) and guanine (G), and between adenine (A) and thymine (T), but not between uracil (U) and thymine (T) or guanine (G). Therefore, the strongest hydrogen bonding occurs between cytosine and guanine, making choice E the correct answer.
