Which is not a difference between B-DNA and A-DNA?

#Section 2: General Biology

  1. A-DNA forms under more dehydrating conditions than B-DNA.

  2. For polynucleotide strands containing the same number of nucleotides, the A-DNA strand will be shorter from end-to-end than the corresponding B-DNA.

  3. Both are helical, but B-DNA is right-handed and A-DNA is left-handed.

  4. The planes of the nitrogenous bases are not perpendicular to the helix axis in A-DNA.
