The enzyme that can proofreads replicating DNA, detects incorrect bases, excises them, and correctly replaces them is
A)DNA ligase
B)DNA polymerase
C)DNA helicase
D)DNA gyrase
E)Primase

Question

Quizplus · Accepted Answer

The enzyme that has the ability to proofread replicating DNA and correct errors is DNA polymerase. It detects any incorrect bases, excises them, and replaces them with the correct bases. DNA ligase's function is to join the ends of DNA fragments together, DNA helicase unwinds the double-stranded DNA, DNA gyrase relieves the tension created during the replication process, and primase is responsible for synthesizing RNA primers.
