What enzyme(s)is/are responsible for removal of RNA primers and joining of Okazaki fragments?
A)DNA polymerase I
B)DNA polymerase III
C)DNA ligase

E)DNA polymerase III and DNA ligase

Question

Quizplus · Accepted Answer

DNA polymerase I is responsible for removing RNA primers during DNA replication while DNA ligase joins Okazaki fragments. Therefore, the correct choice is DNA polymerase I and DNA ligase. DNA polymerase III is responsible for synthesizing the new DNA strands during replication but not for the removal of RNA primers or joining of fragments.
