Considering the following eukaryotic DNA polymerases,which of the following has the highest fidelity?

Question

Quizplus · Accepted Answer

DNA polymerase delta (pol δ) has the highest fidelity among the eukaryotic DNA polymerases. Pol δ has a proofreading exonuclease activity that can correct errors during DNA synthesis. Pol α lacks proofreading activity and is involved in the initiation of DNA synthesis, while pol β is involved in base excision repair and has lower fidelity than pol δ. Pol ζ is an error-prone polymerase that can introduce mutations during DNA synthesis. Therefore, the correct answer is C, as pol δ has the highest fidelity.
