_____ relieves the tension on the double helix during DNA replication.
A)Helicase
B)Topoisomerase
C)DNA polymerase
D)A single-stranded binding protein
E)An RNA primer

Question

Quizplus · Accepted Answer

Topoisomerase relieves the tension on the double helix during DNA replication by temporarily breaking one or both strands of the DNA molecule, allowing it to rotate around the unbroken strand(s) and relieve the tension. Helicase unwinds the double helix, DNA polymerase adds new nucleotides to the growing DNA strand, single-stranded binding proteins stabilize the separated DNA strands, and an RNA primer is necessary for DNA polymerase to begin adding nucleotides during replication, but none of these directly relieve tension on the double helix.
