This review addresses chromosome partitioning in Escherichia coli and
Bacillus subtilis. The first part deals with events associated with co
mpletion of a round of replication to an extent that yields separable
chromosomes. Events more directly involved in chromosome movement are
covered in the second part. In the final section, a model for chromoso
me partitioning based on the information presented in the first two pa
rts is presented.
