Which enzyme functions to prevent supercoiling of the dna molecule during replication?

The enzyme Topoisomerase functions to prevent super-coiling of the  DNA molecule during replication.

Explanation:

During replication, topoisomerases are required to relieve the positive supercoiling that arises from DNA unwiding mediated by Helicases.A DNA topoisomerase is a nuclease that breaks a phosphodiester bond in a DNA strand.All topoiomereases are classified as  Topoisomerase I and Topoisomerase II  depending on whether they cleave one or two strands respectively.Topoisomerase I do not use ATP as a source of energy, the reaction is powered by energy stored in super-coiled DNA.Topoisomerase II also do not require external energy but it utilizes ATP hydrolysis to drive conformation changes in the protein during reaction cycle.

Plants take energy from the sunlight with the of chlorophyll so the plant starts the food chain. then an herbivore eats the plant and gets its energy.then a carnivore or a human eats the herbivore and gets its energy. : )
