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.

the level of progesterone is low at the pre-ovulatory phase of the cycle but it gradually increases and the levels are high at the luteal phase. if pregnancy occurs, the level of progesterone will be high throughout the pregnancy.

if egg is fertilized and the mother gets pregnant, progesterone starts preparing the uterus for the implantation. it starts building up the lining of uterus and make it hostile of the period of pregnancy.
