Question

Quizplus · Accepted Answer

PCNA is a sliding-clamp protein that forms a ring around DNA, allowing DNA polymerase to remain attached and thus increasing its processivity during DNA replication. A is incorrect because PCNA is not a DNA polymerase; it only interacts with DNA polymerase. C is incorrect because it is not a single-stranded DNA binding protein. D is incorrect because it is not an origin-of-replication binding protein.
