Bacterial cells have an important mechanism to help manage chromosomes, which is to condense them after DNA replication. If the daughter chromosomes are condensed, they do not overlap as much in the cell and so are less apt to become interlinked. Condensation of chromosomes prior to mitosis has been known for a long time to occur in eukaryotic cells, where the chromosomes are only clearly visible just before mitosis. We now know that bacteria also condense their daughter DNAs to make them easier to manage, even though it is more difficult to visualize the condensation of bacterial chromosomes because of their smaller size.
