Immediately after dna replication a dna repair mechanism scans the dna for incorrect base pairs. upon which feature of the dna molecule does the repair mechanism rely to indicate incorrect bases?

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.

explanation:

after a the power stroke, adp is released, but the cross-bridge formed is still in place. atp then binds to myosin, moving the myosin to its high-energy state, releasing the myosin head from the actin active site.
