DNA Polymerase is the enzyme which adds new nucleotides during  replication.
DNA polymerase is the enzyme responsible for synthesizing a new strand of complimentary DNA. After another enzyme (a DNA helicase) has seperated two orginal strands of DNA, the polymerase moves along the template strand and polymerizes free nucleotides into a new antiparallel strand.
