The difference between topoisomerase I and topoisomerase II is that A. topoisomerase I precedes the DNA replisome while topoisomerase II does not. B. topoisomerase I generates single strand nicks while topoisomerase II generates double strand nicks. C. topoisomerase I is the only one that can relax supercoils. D. topoisomerase I generates double strand nicks while topoisomerase II generates single strand nicks. E. topoisomerase II is the only one that can relax supercoils.

Enzymes that can alter DNA supercoiling are called topoisomerases. Identify the following as characteristics of type I topoisomerases or type II topoisomerases and sort accordingly: Items: Cleaves one strand of the DNA double helix ATP - independent ATP- dependent Cleaves two strands of the DNA double helix Introduces supercoils Unwinds supercoils Categories: Type I Type II
