Question

One of these enzymes called "terminal transferase," or "TdT," is central to the TUNEL assay. Some functionality of one of these enzymes is maintained in the cleaved "large" Klenow fragment. These enzymes produce (0[1])concatemers (20[1])in a repetitive "rolling circle" process. A homotrimer that serves as a processivity factor for one of these enzymes is the "sliding clamp" PCNA. These enzymes, whose activity follows strand invasion, catalyze (*) synthesis (0[1])that occurs alongside the activity of both topoisomerases and helicases. Ligation is needed to combine the Okazaki fragments synthesized by the "delta" one of these enzymes on the lagging strand during replication. For 10 points, name these proteins that make new DNA. ■END■ (10[2])

ANSWER: DNA polymerases [accept DNA Polymerase I or DNA Polymerase III or DNA Polymerase kappa or DNA Polymerase delta; prompt on polymerases; accept answers without "DNA" at the end; reject "RNA polymerases"]
