C)Topoisomerase II
D)DNA polymerase

Question

Quizplus · Accepted Answer

RNA primase is the first enzyme to synthesize a nucleic acid at a replication fork. Its function is to synthesize short RNA primers that serve as a starting point for DNA polymerase III to begin synthesizing new DNA strands. Helicase unwinds the DNA double helix, Topoisomerase II relieves the tension caused by the unwinding process, and DNA polymerase III is responsible for synthesizing new DNA strands. However, RNA primase is the first enzyme to initiate the synthesis of nucleic acids during DNA replication.
