Within a double-stranded DNA molecule, if adenine forms hydrogen bonds with thymine, and cytosine forms hydrogen bonds with guanine what consequence in the structure of the DNA?
A) It allows variable width of the double helix.
B) It permits complementary base pairing.
C) It determines the tertiary structure of a DNA molecule.
D) It determines the type of protein produced.

This base pairing (adenine with thymine, and cytosine with guanine) permits complementary base pairing, which is fundamental for the accurate replication of DNA and the transcription of RNA. It ensures that each strand can serve as a template for the creation of a new complementary strand.
