DNA Polymerases are responsible for the addition of nucleotides to the new strand of DNA, and for replacing the RNA primers.
DNA polymerases catalyze the process of adding DNA nucleotides to a new strand of DNA. Some DNA polymerases also proof read and correct errors so as to conserve the DNA sequence.
The two main ones are DNA-polymerase and helicase
DNA polymerase
In humans, many enzymes are involved in DNA replication. Among them are: DNA polymerase I DNA polymerase III Ligase Primase Helicase DNA polymerase I and III perform the bulk of the actual reproduction--their job is to add nucleotides to the growing strands. The others perform specialized functions and are essential to the process.
transcription: produces RNA, initiation and elongation of RNA chains from a DNA template
DNA polymerase matches the bases on the parent strand.
Short Answer: There are almost a dozen different types of DNA polymerase: some may have a subunit that performs the unwinding functions.
Primase in the DNA-dependent RNA polymerase enzyme that functions in DNA replication by synthesizing the RNA primers which are then extended by DNA polymerase to yield newly synthesized DNA fragments. While being an RNA polymerase, primase is different from the RNA polymerase that functions in the transcription of DNA.
DNA polymerase is a catalyst, by catalyzing the synthesis of new DNA by adding nucleotides to a preexisting chain. There are several different DNA polymerases, but DNA polymerase I and DNA polymerase II play the major roles in DNA replication.
DNA Helicase is the major enzyme involved in the replication of DNA. The reason why it is so important is that it unwinds the DNA which creates two separate strands.

DNA Polymerase.
DNA Polymerase is the enzyme which adds new nucleotides during replication.
transcription: produces RNA, initiation and elongation of RNA chains from a DNA template
DNA polymerase replicated DNA. RNA polymerase creates mRNA to be used in protein synthesis. RNA polymerase does not replicated DNA.
DNA polymerase matches the bases on the parent strand.
