The answer is Topoisomerase.
<span>Topoisomerase is an enzyme with the role to regulate the overtwisting or </span>undertwisting<span> of DNA helix. If DNA helix is untwisted, topoisomerases will regulate this situation and will twist DNA helix.</span>
Nuclease<span> is an enzyme that cleaves the sequences of nucleic acids into smaller units.</span>
