Bacterial Chromosome Segregation
Annual Review of Microbiology, 2002▪ Abstract Recent studies have made great strides toward our understanding of the mechanisms of microbial chromosome segregation and partitioning. This review first describes the mechanisms that function to segregate newly replicated chromosomes, generating daughter molecules that are viable substrates for partitioning.

Critical Reviews in Biochemistry and Molecular Biology, 2008
Bacteria represent the vast majority of biological diversity found on Earth. In this review, we focus on selected aspects of their genetic material, those providing insight into structural, functional, dynamic, and evolutionary aspects of their genomes. Bacterial chromosomes are far more dynamic than previously realized, and dozens of mechanisms giving

Bacterial chromosome origins of replication
Current Opinion in Genetics & Development, 1993Bacteria regulate chromosomal replication from one specific origin. We compare the regulatory requirements, DNA structures, and biochemical properties of the prototypic Escherichia coli origin with those of evolutionarily distant Bacillus subtilis and Caulobacter crescentus origins.

Replication of the bacterial chromosome
Proceedings of the Royal Society of London. Series B. Biological Sciences, 1966In this paper I shall confine myself to only one aspect of chromosome replication in bacteria: its control and co-ordination with growth and cell division. The nature of the problem to be considered is made clear by two features of chromosome replication in Escherichia coli , First, under conditions of rapid growth,

On the growth mechanism of the bacterial chromosome
Journal of Molecular Biology, 1963Physical methods have been used to determine the number of growth points on the DNA of E. coli bacteria. The thymine analogue [14C]5-bromouracil was incorporated into DNA for varying short times. The labelled DNA was isolated with a molecular weight of 4 × 107. The density distribution of the radioactivity was investigated in CsCl gradients.

Segregation of the Bacterial Chromosome
1998Bacteria must successfully complete several processes of the cell cycle to ensure that a single cell will become two viable daughter cells. These processes include: 1) replication of the chromosome, 2) segregation of the chromosomes to opposite poles, and 3) cell division.

The structure and function of the bacterial chromosome
Current Opinion in Genetics & Development, 2005Advances in microscopic and cell biological techniques have considerably improved our understanding of bacterial chromosome organization and dynamics. The nucleoid was formerly perceived to be an amorphous entity divided into ill-defined domains of supercoiling that are randomly deposited in the cell. Recent work, however, has demonstrated a remarkable

Physics of the Bacterial Chromosome
AIP Conference Proceedings, 2006Genomic DNA in bacteria is concentrated in a distinct structure, the bacterial chromosome or nucleoid [Pettijohn, D.E. (1996) The Nucleoid.

The choreographed dynamics of bacterial chromosomes
Trends in Microbiology, 2005Despite decades of study, the exquisite temporal and spatial organization of bacterial chromosomes has only recently been appreciated. The direct visualization of specific chromosomal loci has revealed that bacteria condense, move and position their chromosomes in a reproducible fashion.
