Question

Quizplus · Accepted Answer

DNA Polymerase I has polymerase activity, 5' → 3' exonuclease activity for removing primers, and 3' → 5' exonuclease activity for proofreading. It does not have the ability to nick intact double-stranded DNA; this function is typically associated with enzymes like nucleases or specific restriction enzymes.
