Research over the last two decades has revealed that bacterial genomes are, in fact, highly organized. The goal of future research is to understand the molecular mechanisms underlying bacterial chromosome architecture and dynamics during the cell cycle. Here we discuss techniques that can be used with live cells to analyze chromosome structure and segregation in the gram-positive model organism Bacillus subtilis.
