What Is The Proofreading Function Of DNA Polymerase? DNA polymerase proofreading is a spell-checking activity that enables DNA polymerases to remove newly made nucleotide incorporation errors from the primer terminus before further primer extension and also prevents translesion synthesis. Which DNA polymerase has proofreading activity? In bacteria, all three DNA polymerases (I, II and III)

Is There Proofreading In PCR?

Is There Proofreading In PCR? Proofreading PCR (PR-PCR) was developed for mutation detection in 1998 but is rarely applied due to its low efficiency in allele discrimination. Here we developed a modified PR-PCR method using a ddNTP-blocked primer and a mixture of DNA polymerases with and without the 3′-5′ proofreading function. Why can polymerase proofread?
