C) DNA ligase
D) Okazaki fragments

Question

Quizplus · Accepted Answer

Processive enzymes are enzymes that remain attached to the substrate for multiple catalytic cycles without releasing it. DNA polymerase III is a processive enzyme that synthesizes the leading and lagging strands of DNA during replication. DNA polymerase I, on the other hand, is not processive and is involved in removing RNA primers and replacing them with DNA nucleotides. DNA ligase seals nicks in the DNA backbone by catalyzing the formation of a phosphodiester bond, and Okazaki fragments are short, discontinuous stretches of DNA on the lagging strand that are eventually joined together by DNA ligase.
