E)primase.

Question

Quizplus · Accepted Answer

The enzyme that can proofread replicating DNA is DNA polymerase. It detects incorrect bases, excises them, and correctly replaces them through the process of exonuclease activity. DNA ligase is responsible for joining the Okazaki fragments on the lagging strand during DNA replication. DNA helicase unwinds the DNA double helix while DNA gyrase helps relieve the tension created during the unwinding process. Primase is responsible for synthesizing a short RNA primer that will initiate DNA synthesis.
