Primers are short fragments of RNA that are synthesized by primase since DNA cannot actually initiate the polynucleotide synthesis. Thus, primers serve as thestarting point for every polynucleotide synthesis needed in DNA replication.
Primers are synthesized _____ on the lagging strand of areplication fork.
A. at the beginning of every Okazaki fragment
B. only at the 3' end of the newly synthesized strand
C. only at the 5' end of the newly synthesized strand
D. It depends on whether the synthesis is continuous ordiscontinuous
E. at multiple places in an Okazaki fragment
