Question

If the pitch of the DNA helix is 3.4 nm and there are 10 base pairs per turn, the rise per base pair is:

Accepted Answer

D. {'text': '0.34 nm', 'label': 'D'}

Rise per bp = pitch / bp per turn = 3.4 nm / 10 = 0.34 nm. The B-form helix is right-handed with a 20 angstrom (2 nm) diameter and 34 angstrom pitch.
