Solution and Explanation
A-DNA and B-DNA both make a right-handed helix. These are the two common forms of DNA found in biological systems. In these structures, the helical twist proceeds in the right direction, meaning that if you were to follow the spiral from the bottom to the top, it would twist clockwise. B-DNA is the most prevalent form under physiological conditions, while A-DNA forms under dehydrating conditions.
