Question

According to the highly specific Watson and Crick double-helix structural model of DNA, which of the following rules strictly governs the complementary base pairing across the two anti-parallel strands?

Prashant Kotian · Accepted Answer

Correct answer: C. Complementary base pairing in the DNA double helix is strictly dictated by specific hydrogen bonding geometries. Adenine () always pairs with Thymine () utilizing exactly two hydrogen bonds, whereas Guanine () pairs with Cytosine () utilizing exactly three hydrogen bonds.
