Z-DNA makes a left-handed helix. Unlike the right-handed twists of A-DNA and B-DNA, Z-DNA has a zigzag backbone, and the helix twists in a left-handed direction. Z-DNA is less common and is often formed under certain physiological or experimental conditions, such as high salt concentrations or negative supercoiling.
