DNA Polymerase I Klenow Fragment N104

DNA polymerase I, the large fragment (Klenow fragment) is the protease hydrolysate of E. coli DNA polymerase I, with 5´→3´ DNA polymerase activity and 3´→5´ exonuclease activity, but 5 is missing ´→3´ Exonuclease activity. The Klenow fragment retains the high fidelity of the holoenzyme without degrading the 5´ end of DNA.
