Describe how RNA polymerase motion along the DNA affects supercoiling and explain how this is resolved
What will be an ideal response?
Ans: As RNA moves along the DNA it generates positive supercoils ahead of it and leaves negative supercoils behind. The enzymes gyrase and topoisomerase are required to introduce and remove negative supercoils, respectively, to restore normal coiling of DNA.
