What strategies do cells use to ensure that newly replicated DNA does not contain errors? DNA polymerase replaces the newly replicated DNA on any chromosomes on which there are mistakes. Enzymes remove and resynthesize any misshapen sequences in the DNA prior to replication. Enzymes repair mistakes in the new DNA double helix after the new double helix separates from the original double helix. As DNA polymerase synthesizes new DNA, the DNA polymerase finds and corrects misplaced nucleotides. Enzymes proofread the DNA after the DNA has been replicated and replace any mismatched nucleotides.

Enzymes proofread the DNA after the DNA has been replicated and replace any mismatched nucleotides.

Explanation:

DNA replication occurs to make exact copy of original DNA. Transcription of genetic information to an intermediate mRNA occur after replication after which we have translation of genetic information into amino acids.

In the process of replicating DNA error can occur and then enzymes proofread the work for errors. Enymes DNA polymerase proofs read the replication, removes and replace the nucleotide base from where error occurs. It proof read after the DNA replication has occured.

This enzyme is also involve in DNA replication.
