Bacterial chromosome segregation.
Dividing cells have mechanisms to ensure that their genomes are faithfully segregated into daughter cells. In bacteria, the description of these mechanisms has been considerably improved in the recent years. This review focuses on the different aspects of bacterial chromosome segregation that can be understood thanks to the studies performed with model organisms: Escherichia coli, Bacillus subt...
متن کاملBacterial chromosome segregation.
In most bacteria two vital processes of the cell cycle: DNA replication and chromosome segregation overlap temporally. The action of replication machinery in a fixed location in the cell leads to the duplication of oriC regions, their rapid separation to the opposite halves of the cell and the duplicated chromosomes gradually moving to the same locations prior to cell division. Numerous protein...
متن کاملBacterial chromosome segregation.
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. Then experiments that address the mechanisms of bulk chromosome movement are summarize...
متن کاملBacterial chromosome organization and segregation.
Bacterial chromosomes are generally approximately 1000 times longer than the cells in which they reside, and concurrent replication, segregation, and transcription/translation of this crowded mass of DNA poses a challenging organizational problem. Recent advances in cell-imaging technology with subdiffraction resolution have revealed that the bacterial nucleoid is reliably oriented and highly o...
متن کاملLinear ordering and dynamic segregation of the bacterial chromosome.
O rganization is a hallmark of life (1). As observational methods have improved, the extent of organization that is revealed has grown continuously. It was once thought that the bacterial nucleoid might be the last refuge of entropy because of its amorphous appearance in micrographs. This view was undermined by the demonstration that a few specific sequences, such as the origin and terminus of ...
