DNA Replication Proofreading activity to maintain the fidelity of DNA synthesis occurs after the synthesis has been completed occurs in prokaryotes but not eukaryotes is a function of the 3'-5' exonuclease activity of the DNA polymerases requires the presence of an enzyme separate from the DNA polymerases occurs after the synthesis has been completed occurs in prokaryotes but not eukaryotes is a function of the 3'-5' exonuclease activity of the DNA polymerases requires the presence of an enzyme separate from the DNA polymerases ANSWER DOWNLOAD EXAMIANS APP
