I made an one step gene disrruption, and after we transformed our
strain with the linear DNA fragment bearing the target gene with an
insertion, a gene replacement event took place as confirmed by southern
blot. We don't detected any strange behavior in our system. I would like
to know what kind of misinterpretations could arise from that.
