How many complete rotations would MOST likely correspond to a positively supercoiled DNA molecule that is 100 bp in length?

Question

Quizplus · Accepted Answer

A positively supercoiled DNA molecule has more twists than the normal relaxed state. Typically, a relaxed DNA has about 10.5 base pairs per turn, so 100 bp would have about 9-10 turns. A positively supercoiled DNA would have more turns, making 15 a plausible choice.
