Web26 mei 2006 · Accurate chromosome segregation during meiosis and mitosis is essential for the maintenance of genomic stability. Defects in the regulation of chromosome segregation during division predispose cells to undergo mitotic catastrophe or neoplastic transformation. Cohesin, a molecular glue holding sister chromatids together, is … WebAbstract The question of whether mitotic segregation of chromatids is random or programmed assumes great significance for cellular differentiation if one recognizes that …
Web22 mei 2006 · Nevertheless, SAC activity is required for proper sister chromatid segregation at the metaphase–anaphase II transition [84]. Furthermore, recent work in Drosophila has shown that the permanent mitotic arrest of the three meiotic products that do not participate in zygote formation but which remain within the developing embryo … Web7 jul. 2024 · In anaphase, the paired chromosomes ( sister chromatids) separate and begin moving to opposite ends (poles) of the cell. Spindle fibers not connected to chromatids lengthen and elongate the cell. At …
WebResults Chromosome segregation in spo13Δ. We began by studying chromosome behavior in the single meiotic division that occurs in cells lacking Spo13. Diploids homozygous for the spo13Δ mutation undergo a single meiotic division, forming dyads. Chromosome segregation is mixed, as sister chromatids segregate away from one another in some … Web7 nov. 2024 · Here, we report a series of spatiotemporally regulated asymmetric components, which ensure biased sister chromatid attachment and segregation during ACD of Drosophila male germline stem cells (GSCs).
