DNA polymerase is involved in the process of DNA replication. There are different types,some are named below:
DNA polymerase 3 is thought to be the most important one and is involved in DNA elongation. It is fast (1000 bases per second), processive (1000-5000 bases added before polymerase falls off DNA), accurate and works in the 5' to 3' direction.
DNA polymerase 1 has proof-reading activity. It is slow and non-processive and only adds a few bases to the chain. It also removes RNA primers.
