Mechanisms for chromosome segregation

Current Opinion in Microbiology, 2014
Bacteria face the problem of segregating their gigantic chromosomes without a segregation period restricted in time and space, as Eukaryotes do. Segregation thus involves multiple activities, general or specific of a chromosome region and differentially controlled. Recent advances show that these various mechanisms conform to a “pair and release” rule,

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.

CHROMOSOME SEGREGATION IN YEAST

Annual Review of Microbiology, 1993
Because of their genetic tractability, much has been learned concerning the mechanisms of chromosome segregation in budding yeast, Saccharomyces cerevisiae, and fission yeast, Schizosaccharomyces pombe. This chapter reviews the cytology and molecular and cell biology of mitosis in both of these yeasts.

Plasmid and chromosome segregation in prokaryotes

Trends in Microbiology, 2000
Recent major advances in the understanding of prokaryotic DNA segregation have been achieved by using fluorescence microscopy to visualize the localization of cellular components. Plasmids and bacterial chromosomes are partitioned in a highly dynamic fashion, suggesting the presence of a mitotic-like apparatus in prokaryotes.

Chromosome segregation and genomic stability

Current Opinion in Genetics & Development, 2004
The acquisition of genomic instability is a crucial step in the development of human cancer. Genomic instability has multiple causes of which chromosomal instability (CIN) and microsatellite instability (MIN) have received the most attention. Whereas the connection between a MIN phenotype and cancer is now proven, the argument that CIN causes cancer ...

Mechanisms for Chromosome and Plasmid Segregation

Annual Review of Biochemistry, 2006
The fundamental problems in duplicating and transmitting genetic information posed by the geometric and topological features of DNA, combined with its large size, are qualitatively similar for prokaryotic and eukaryotic chromosomes. The evolutionary solutions to these problems reveal common themes.

Segregation of the Bacterial Chromosome

1998
Bacteria 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.
