What is the function of dna polymerase iii?

The second two activities of DNA Pol I are important for replication, but DNA Polymerase III (Pol III) is the enzyme that performs the 5'-3' polymerase function. Primase - The requirement for a free 3' hydroxyl group is fulfilled by the RNA primers that are synthesized at the initiation sites by these enzymes. read more

Proofreads DNA. (about 20 at a time before it dissociates). It is a 5' to 3' DNA polymerase but also has 5' to 3' and 3' to 5' exonuclease activity to "proof read" and "correct" mismatches. It works with DNA:DNA as well as RNA:DNA. It is responsible to replacing Okazaki RNA fragments with DNA fragments. read more

The enzyme DNA polymerase III is the primary enzyme involved with bacterial DNA replication. It performs the 5'-3' polymerase function, which means that it adds nucleotides to the 3' end of the forming DNA strand during replication. read more

DNA polymerase III holoenzyme is the primary enzyme complex involved in prokaryotic DNA replication. It was discovered by Thomas Kornberg (son of Arthur Kornberg) and Malcolm Gefter in 1970. read more
