Dicentric Chromosome DNA Stretching

Sequential images of a yku70 mutant cell (strain KBY3124) containing a lacO marked dicentric chromosome III showing critical stages in the formation of a stretched lacO array.

Sequential images of a KBY3124 cell showing steps in the resolution of a stretched lacO array.

Unequal distribution of lacO DNA is observed in KBY3124 cells following the resolution of DNA stretching events.
