Mitotic spindle vs spindle fibers
Web26 jul. 2024 · The mitotic spindle is responsible for the accurate segregation of chromosomes into two daughter cells during cell division. The kinetochores of the chromosome are attached to the spindle by the kinetochore fibers (k-fibers), which are discrete bundles of parallel microtubules emanated from the centrosome. Web26 jul. 2024 · Aberrant centrosome activities in mutants of Dictyostelium discoideum result in anomalies of mitotic spindles that affect the reliability of chromosome segregation. Genetic instabilities caused by these deficiencies are tolerated in multinucleate cells, which can be produced by electric-pulse induced cell fusion as a source for aberrations in the mitotic …

Meanwhile, during meiosis, the spindle fibers are referred to as the meiotic spindle.
WebProper kinetochore “geometry” is not sufficient for correct chromosome attachment, since, for example, transient malorientation of chromosomes on the mitotic spindle is frequent during prometaphase even if sister kinetochores are properly assembled on opposite sides of the chromosome.
