The enzyme responsible for relaxing supercoiled dna to allow for the initiation of replication is called

DNA gyrase or topoisomerase II is a correct answer

Explanation:

DNA gyrase belongs to the subclass of topoisomerases type II.

It works as a molecular motor as they get energy from the ATP hydrolysis and gyrase introduces negative supercoil in the DNA.

The enzyme responsible for relaxing supercoiled DNA to allow for the initiation of replication is called DNA gyrase or topoisomerase II.

DNA gyrase function is to relax the supercoiled DNA by introducing negative supercoils into the DNA during the replication, which reduces the superhelical tension and to allow for the initiation of replication.
