T4 DNA Polymerase N101

In the presence of templates and primers, T4 DNA polymerase catalyzes the synthesis of DNA along the 5´→3´ direction. This enzyme also has 3´→5´ exonuclease activity, which is stronger than DNA polymerase I. Unlike DNA polymerase I, T4 DNA polymerase does not have 5´→3´ exonuclease activity.
