WebDifferent DNA polymerases perform specific functions. In prokaryotes, DNA polymerase III is the main enzyme responsible for replication. DNA polymerase I and II have a role to play in repair, removing the primer and filling the gaps. In eukaryotes, DNA polymerase 𝝳 is the main enzyme for replication. WebAdults with the DNA pol III mutation will have fewer mutations than the general population. When DNA pol III is mutated, it loses function, resulting in decreased exonuclease activity and, as a result, a somewhat higher mutational load than normal. As a result, this is an inaccurate response. Most popular questions for Biology Textbooks .
