In the Watson-Crick model for the DNA double helix (B form) the A-T and G-C base pairs share which property?
A) The distance between the two glycosidic (base-sugar) bonds is the same in both base pairs, within a few tenths of an angstrom.
B) The molecular weights of the two base pairs are identical.
C) The number of hydrogen bonds formed between the two bases of the base pair is the same.
D) The plane of neither base pair is perpendicular to the axis of the helix.
E) The proton-binding groups in both base pairs are in their charged or ionized form.

The distance between the two glycosidic bonds is nearly the same in both A-T and G-C base pairs, which is crucial for the uniform structure of the DNA double helix.
