Some hyperthermophilic archaea contain genomes with positive supercoiling generated by ________, which protect DNA from melting at high temperatures.

Question

Quizplus · Accepted Answer

Reverse gyrase is an enzyme that introduces positive supercoiling into DNA to protect it from melting at high temperatures. This is particularly important for hyperthermophilic archaea that live in extreme environments with high temperatures. The other options listed (helicase, polymerase, primase, and reductase) do not play a role in introducing positive supercoiling into DNA.
