The answer is proofreading feature of DNA polymerase.  As the DNA polymerase III replicates DNA, it has a proofreading mechanism in one of the subunits of the holoenzyme. This subunit detects a bad conformation in the double helix when the wrong base pair is placed. In this case, the DNA polymerase III backs up a bit and waits for the exonuclease to nick out the misplaced base.
