Fig. 12: DNA Replication by Complementary Base Pairing: Replacing RNA Primer with DNA

Eventually, DNA polymerase II digests away the RNA primer and replaces the RNA nucleotides of the primer with the proper DNA nucleotides to fill the gap. Finally, the DNA fragments on the lagging strand are hooked together by the enzyme DNA ligase.
