Solution

Answer:

The polymerase activity was found to extend more slowly from an improperly base-paired 3\' terminus. Hence, a mismatched base has a longer residence time at the 3\' terminus than a correctly matched base, and this time increases the probability that the mismatched nucleotide will move to the 3\' exonuclease site and be excised.
