A. Underwinding of a B-DNA helix might facilitate or stabilize the formation of Z-DNA.

B. Underwinding aids in the transition by providing a local region of unwound DNA that allows the shift to Z-DNA.

C. Overwinding of a B-DNA helix might facilitate or stabilize the formation of Z-DNA.

D. Overwinding aids in the transition by providing a local region of unwound DNA that allows the shift to Z-DNA.
