Answer:
Both DNA polymerases have exonuclease activity.
Step-by-step explanation:
1. DNA polymerases are enzymes which replicates DNA during S phase of cell cycle.
2.Both eukaryotes and prokaryotes contain DNA polymerase enzymes.
3. As here, DNA pol I and DNA pol III functions; both DNA polymerases have exonuclease activity as, If the polymerase detects an incorrectly paired nucleotide it has been added, it will remove and replace that incorrectly paired nucleotide with correct nucleotide.
4. Both DNA polymerase I and III adds a nucleotide to the 3' end of a polynucleotide.
