Question

as the two strands of dna are unraveled, which enzyme relieves the strain on the two strands? multiple choice dna endonuclease dna polymerase dna exonuclease dna ligase dna gyrase

Explanation:

DNA gyrase is a type of topoisomerase. When DNA strands are unraveled during processes like replication, super - coiling (strain) occurs. DNA gyrase relieves this strain by introducing negative super - coils. DNA endonuclease cuts DNA at internal sites, DNA polymerase synthesizes new DNA strands, DNA exonuclease removes nucleotides from the end of DNA strands, and DNA ligase joins DNA fragments.

Answer:

DNA gyrase
