How will DNA replication be affected if DNA polymerase I has a mutation that inactivates 5'-to-3' exonuclease activity?
What will be an ideal response?
The 5'-to-3' exonuclease activity of DNA polymerase I removes the RNA primers from the ends of Okazaki fragments. If this activity is missing, the primers may not be removed from the growing DNA strands.
