DNA polymerase are required for

As the question has not specified the type of DNA polymerase whether type I, II & III, So, consider all three & lets have a look of the properties of all 3:- DNA polymerase I  5' → 3' polymerase activity                              5' → 3' exonuclease activity                              3' → 5' exonuclease activity DNA polymerase II   Proofreading, DNA repair DNA polymerase III 5' → 3' polymerase activity                               3'→ 5' exonuclease
