The approximate uniform distance between two strands of B-DNA is

1. a) 34 Angstrom
2. b) 18 Angstrom
3. c) 36 Angstrom
4. d) 20 Angstrom

Answer: d) 20 Angstrom

Explanation: The B-DNA structure is the most stable form of DNA double helix. The width between two strands is approximately 20 Angstrom. The two strands are coiled in a right-handed fashion. The pitch of the helix is 34 Angstrom.
