PCNA stands for proliferating cell nuclear antigen. In prokaryotes three different types of DNA polymerases are found and they are known as DNA Pol I, II and III. In eukaryotes the replication process is more complex and eukaryotes have many types of DNA polymerases. Eukaryotic DNA polymerases are known as DNA Pol α, β,γ, δ and ε. The replication in prokaryotes is simple as compared to eukaryotic DNA replication. PCNA act as a sliding clamp in eukaryotes which is assembled from the specific unit of DNA polymerase δ. In prokaryotes the β-sliding clamp is composed of the β-subunit of the DNA polymerase III. It means PCNA of eukaryotes is similar to the β-subunit of DNA polymerase III. DNA polymerase III is the main enzyme responsible for the replication of leading and lagging strand in prokaryotes. The main enzyme in eukaryotic DNA replication is DNA polymerase δ. It means the function of DNA polymerase III is similar to the function of DNA polymerase δ. Both DNA polymerase ε and DNA polymerase I contain proofreading activities. Both help to correct the error made during the replication by highly processive replication enzymes such as DNA polymerase δ and III. RPC stands for replisome complex protein; this complex is composed of multiple proteins such as helicase, SSBs, DNA polymerase, and primase. It helps in the stabilization of the replication fork during the replication of DNA. The similar function is carried out by the single stranded binding protein known as SSBs.
