Abstract
Bacterial chromosomes are evenly distributed between daughter cells, however no equivalent eukaryotic mitotic apparatus has been identified yet. Nevertheless, an advance in our understanding of the dynamics of the bacterial chromosome has been accomplished in recent years by adopting fluorescence microscopy techniques to visualize living bacterial cells. Here, some of the most recent studies that yield new insights into the nature of bacterial chromosome dynamics are described. In addition, we review in detail the current models that attempt to illuminate the mechanism of chromosome segregation in bacteria and discuss the possibility that a bacterial mitotic apparatus does indeed exist.
