Which of the following is the principal DNA polymerase in eukaryotic leading-strand DNA replication?

Question

Quizplus · Accepted Answer

DNA polymerase δ is the principal DNA polymerase in eukaryotic leading-strand DNA replication. It has a high processivity and proofreading activity, which makes it suitable for replicating long stretches of DNA without making errors. DNA polymerase α (alpha) is involved in initiating DNA synthesis at the replication origins, while DNA polymerase β (beta) is mainly involved in DNA repair. DNA polymerase γ (gamma) is primarily found in mitochondria and is responsible for replicating mitochondrial DNA.
