An example is the recognition of heteroduplex DNA by the mutS protein as a means to detect single base mismatches.

The mechanism of recombination may be different in different organisms.
Both proposed models invoke a heteroduplex DNA before strand resolution to cross-overs or non-cross-overs. This feature is inconsistent with some observations.
