WebThat was my understanding from a class as well - helicase separates the hydrogen bonds between bases (e.g., A, T, C, and G), but thereby creates tension (because a coiled object is being held straight). To relieve this tension (and to keep the DNA from becoming knotted together), topoisomerase clips the DNA into shorter fragments.
