Question
According to the highly rigid and strictly dictated Watson and Crick structural double-helix model of DNA, which of the following definitive rules entirely governs complementary base pairing geometry?
Answer: C
💡 Solution & Explanation
Complementary base pairing in the pristine DNA double helix is chemically unyielding due to highly specific spatial geometries and electron densities. Adenine ($A$) consistently pairs with Thymine ($T$) utilizing exactly two hydrogen bonds, and Guanine ($G$) pairs with Cytosine ($C$) utilizing exactly three hydrogen bonds.
