DNA polymerase 1 has 5' to 3' exonuclease activity which helps in the removal of primer. The similar function is performed by means of FEN1 and RNase H.
That's why the enzymatic activity displayed by DNA polymerase 1 is : Primer removal.
Add Answer to:
. What enzymatic activity displayed by DNA Pol I do eukaryotic polymerases lack that is compensated...

What other DNA polymerases are involved in DNA replication and when are they active? Although Dpb3 and Dpb4 are considered non-essential, DNA polymerase ? dissociates more frequently from the template when Dpb3 and Dpb4 are deleted. What are the explanations for this result? What do you think would happen if, in addition to Dpb3 and Dpb4 deletion, the exonuclease activity of Pol2 was also mutated in such a way that it did not function? How might replication fork progression and...
