DNA Polymerase I catalyzes the template-directed polymerization of nucleotides into duplex DNA in a 5´→3´ direction. DNA Polymerase I possesses a 3´→5´ exonuclease activity or "proofreading" function, which lowers the error rate during DNA replication, and also contains a 5´→3´ exonuclease activity, which enables the enzyme to replace nucleotides in the growing strand of DNA by nick translation (1). The enzyme, purified from r…
