Cell DivisionFor accurate segregation of chromosomes during cell division, microtubule fibres must attach sister kinetochores to opposite poles of the mitotic spindle (bi-orientation). Aurora kinases are linked to oncogenesisand have been implicated in the regulation of chromosome–microtubule attachments....
Cell division during development in many cases generates daughter cells that differ not only in fate, but also in size. We investigate the mechanisms that ensure proper spindle positioning during such asymmetric divisions using the one-cell stage Caenorhabditis elegans embryo as a model system. We ...

Adhesion to the extracellular matrix persists during mitosis in most cell types. However, while classical adhesion complexes, such as focal adhesions, do and must disassemble to enable mitotic rounding, the mechanisms of residual mitotic cell–extracellular matrix adhesion remain undefined. Here, we ide...
Cell divisionMossCell division is a fundamental biological process that has been extensively investigated in different systems. Similar to most eukaryotic cells, plant cells assemble a mitotic spindle to separate replicated chromosomes. In contrast, to complete cell division, plant cells assemble a ...
Along the ventral nerve cord, dorsally to it, there are single Plo-vasa- and Plo-piwi1-positive cells. These cells are spindle-shaped and have a high nuclear–cytoplasmic ratio. The most anterior localization of such cells is at the level of the first postlarval (trunk, not head) segment...
With increasing PEF intensity (200–400 V/cm), the cells appear to become spherical and lose their spindle-like shape. In general, however, the cells retained their integrity and no cell aggregation was observed. Figure 4. Immunofluorescence staining studies of cells subject to the PEF ...
or spread." Each chromosome has two kinetochores. Microtubules that bind a chromosome are called kinetochore microtubules. Kinetochore fibers extend from the kinetochore region and attach chromosomes tomicrotubulespindle polar fibers. These fibers work together to separate chromosomes during cell division. ...
What is the stage of mitosis during which mitotic spindle fibers attach to kinetochores? In what phase is the genetic material in the cell correctly referred to as chromatids? A. Metaphase and telophase B. Anaphase and metaphase C. Interphase and telophase D. In...
