Even though DNA polymerase has a proofreading function, it still introduces errors in the newly synthesized strand at a rate of 1 per 10⁷ nucleotides.To what degree does the mismatch repair system decrease the error rate arising from DNA replication?

Question

Even though DNA polymerase has a proofreading function, it still introduces errors in the newly synthesized strand at a rate of 1 per 107 nucleotides.To what degree does the mismatch repair system decrease the error rate arising from DNA replication?
