Synchronization of chromosome dynamics and cell division in bacteria.
Bacterial cells have evolved a variety of regulatory circuits that tightly synchronize their chromosome replication and cell division cycles, thereby ensuring faithful transmission of genetic information to their offspring. Complex multicomponent signaling cascades are used to monitor the progress of cytokinesis and couple replication initiation to the separation of the two daughter cells. More...
متن کاملSynchronization of cell division in microorganisms by percoll gradients.
We describe a method for obtaining synchronously dividing cells of bacteria (Escherichia coli B and K-12 and Bacillus subtilis 168) and fission yeasts (Schizosaccharomyces pombe) by the use of Percoll density gradients.
متن کاملIn Vitro Cell Cycle Synchronization of Sheep Granulosa Cells
Purpose: To investigate the effect of different methods of synchronization on sheep granulosa cell cycle. Materials and Methods: Granulosa cells were aspirated from ovarian follicles and plated in a DMEM medium containing 15% FBS. Upon 70-80% confluency, the medium of the primarycultured as well as the passaged-5 cells were replaced with the medium containing either 0.5% FBS for 24, 48 and 72 h...
متن کاملDivision synchronization in a respiratory deficient yeast.
Synchronization of cell division in a variety of microorganisms has been achieved by temperature shifts or by starvation. Two reports exist which mention svnchronization of the budding process in yeast by starvation (Beam et al., 1954; Ogur et al., 1953). In both cases, the demonstration of synchronization was incidental to the primary purpose of the experiments performed, and was therefore not...
