Which of the following removes the RNA nucleotides from the primer and adds equivalent DNA nucleotides to the 3' end of Okazaki fragments?
A)helicase
B)DNA polymerase III
C)ligase
D)DNA polymerase I
E)primase

Question

Quizplus · Accepted Answer

DNA polymerase I removes RNA nucleotides from the primer and fills the gap by adding equivalent DNA nucleotides in the 5' to 3' direction. This process is important in the synthesis of the lagging strand, where Okazaki fragments are synthesized in the opposite direction of the replication fork. DNA polymerase III is responsible for elongating the leading and lagging strands, helicase unwinds the double helix, ligase joins the Okazaki fragments, and primase synthesizes RNA primers.
