Abstract
A novel way to study the pattern of chromosome segregation in bacteria is presented. It uses bacterial sporeformers having spores which are non-randomly located in the sporangia with respect to the “old” and the “new” poles. Such spores can be used as topological markers to distinguish between the three basic kinds of DNA segregation models: random, partially deterministic (mixed), and deterministic, by monitoring segregated labeled DNA strands occurring in spores. The major assumption of using bacterial sporeformers to study DNA strand segregation is that sporulation and cell division segregations are analogous. The three basic kinds of segregation models are presented for bacterial species with haploid and diploid spores, and are discussed with reference to the available data from DNA strand segregation studies in vegetative and sporulating cells.
