Which of the following is true of the primers used during DNA replication?
A) They are involved in the synthesis of only the lagging daughter strands.
B) They are involved in the synthesis of only the leading daughter strands.
C) They are involved in the synthesis of both leading and lagging daughter strands.
D) None of these, primers are not involved in the synthesis of either daughter strand.

Question

Quizplus · Accepted Answer

Primers are short RNA sequences that are synthesized by primase and provide a starting point for DNA polymerase to begin replication. They are required for the synthesis of both leading and lagging daughter strands, as DNA polymerase can only add nucleotides to an existing 3'-OH group on a nucleic acid chain, and cannot initiate synthesis on its own. Therefore, both the leading and the lagging strands require primers to initiate replication.
