Question

The following statements refer to the E.coli repticative DNA polymerase: A. DNA Pol I displays very limited processivity and possesses 3'--) 5' exonuctease activity. allowing fidelity of DNA replication. B. DNA Poi III Is suitable for leading strand DNA synthesis due to Its high processivity and 5'—) 3' exonuclease activity that removes incorrect nucleotides incorporated during DNA synthesis. C. DNA Pol I possesses 5'--* 3' exonuclease activity which allows removal of the RNA primer while as 5'-' 3' polymerase activity allows it to fill the gap created by removal of the RNA primer D. DNA Pol III is suitable for lagging strand DNA synthesis due to its low processivity and 5'-' exonuctease activity. Which one of the options below represents the combination of all correct statements?
