Verified Answer
What happens to supercoil during DNA replication?
The DNA strand that has not been cleaved is then passed through the single-stranded break. The cleaved strand is then resealed, forming a structure with the same chemical bonds as the starting DNA, but with one less negative supercoil. By this mechanism, the enzyme removes one negative supercoil at a time.
