DNA Polymerase is the enzyme which adds new nucleotides during  replication.
Helicase:Unwinds ds DNA at the replication fork. DNA polymerase:Involved in synthesis of new DNA strand in 5' to 3' direction.Also performs proof reading and nick translation. Primase:Provides a platform for DNA polymerase for synthesis of new strand. Telomerase:Adds length to the ends of DNA by adding repititive nucleotide sequences in the end.
