Which of the following is NOT a characteristic of a double-stranded DNA helix. The width of the helix is 20 Angstroms. Bases are separated by 10 Angstroms. The length of one helical turn is 34 Angstroms. All these statements are true.
There are approximately 10 turns in a 100-angstrom-long B-DNA double helix.
