The effect on DNA replication of mutations that destroyed 3 ′ → 5 ′ exonuclease activity of DNA polymerase I. Introduction: A change in the genetic code during replication is termed as “mutation”. Mutation can occur during replication or recombination. It is a permanent alteration in the nucleotide sequence in DNA . Cells have evolved many “repair mechanisms” due to the lethal potential of DNA mutations. Mutation that can mutate damaged DNA are, “substitution”, “deletion” or “insertion” of base pairs.
