chromosome segregations การใช้

• There is evidence that CO recombination facilitates meiotic chromosome segregation.
• During cell division, heterochromatin formation is required for proper chromosome segregation.
• This gene encodes a kinase involved in spindle checkpoint function and chromosome segregation.
• The Aurora B kinase is a chromosome passenger protein and regulates chromosome segregation and cytokinesis.
• Failure of centrosome regulation can cause mistakes in chromosome segregation and is associated with aneuploidy.
• Required for chromosome segregation at metaphase-anaphase transition, robust mitotic spindle formation and cytokinesis.
• To ensure that chromosome segregation takes place correctly, cells have developed a precise and complex mechanism.
• During mitosis chromosome segregation occurs routinely as a step in cell division ( see mitosis diagram ).
• CDC5 is believed to have roles in sister-kinetochore coorientation and chromosome segregation during meiosis I.
• Overall, it plays a vital role in heterochromatin organization, chromosome segregation, and mitotic progression.
• Thus, the kinetochore is essential for the chromosome segregation that is classically associated with mitosis and meiosis.
• In eukaryotic cells chromosome segregation into the daughter cells is not initiated until replication is complete in all chromosomes.
• Aside from microtubules it also contains various proteins involved in cytokinesis, asymmetric cell division, and chromosome segregation.
• Roles of the microtubule cytoskeleton include mechanical support, organization of the cytoplasm, transport, motility and chromosome segregation.
• The precise orientation of this complex is required to ensure accurate chromosome segregation and to specify the cell division plane.
• :The centromere is the chromosomal site that organises and regulates the machinery responsible for chromosome segregation to daughter cells.
• The fly and yeast models have revealed that Polo kinases coordinate the more complex pattern of chromosome segregation in meiosis.
• Indeed, it has also been shown that laser ablation of centrosomes in vertebrate cells inhibits neither spindle assembly nor chromosome segregation.
• This fact can be exploited in a laboratory setting by using colchicine to inhibit chromosome segregation during meiosis, creating synthetic autopolyploid plants.
• Microtubules have a key role in mitosis : they generate the mitotic spindle assembly, which allows chromosome segregation and the cell division.
