Answer: The answer is option B) It checks DNA for errors during replication
Explanation:
In DNA replication, the DNA strands are first separated by the breaking of the hydrogen bonds between base pairs, then the base composition of each of the parental strand is checked by the enzyme known as DNA POLYMERASE, which has very high proof reading ability.
Once each strand has been cleared to be free of errors due to mutation, then the DNA polymerase catalyzes the polymerization of a complimentery strand.
The above illustrates how DNA polymerase prevents mutations.
