DNA Polymerase is the enzyme which adds new nucleotides during  replication.
DNA polymerases Enzymes that bring about the synthesis of a daughter strand of DNA on the basis of a complementary DNA template. They are involved in DNA replication and repair, and act by adding deoxynucleotide triphosphates to the 3â-OH group of the new DNA strand. These enzymes not only synthesize new DNA but proof-read the new strand and remove incorrect nucleotides and replace them with the correct ones.
