In DNA molecules, complementary base pairing occurs between ____.
A)cytosine and uracil
B)adenine and guanine
C)adenine and uracil
D)adenine and thymine
E)sugar and phosphate

Question

Quizplus · Accepted Answer

Complementary base pairing occurs between adenine and thymine (A-T) and between cytosine and guanine (C-G) in DNA molecules. Uracil only pairs with adenine in RNA molecules, not in DNA. Sugar and phosphate molecules make up the backbone of the DNA molecule, but they do not participate in the complementary base pairing.
