Answer:
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.
The answer is D and i think it’s pretty obvious
