WebJan 28, 2024 · Microtubules that will eventually form the mitotic spindle extend between the centrosomes, pushing them farther apart as the microtubule fibers lengthen. In anaphase, … WebHow do microtubules shorten in anaphase? If this concept is correct, the spindle microtubules attached to the kinetochores of the sister chromatids, shorten by depolymerization (removal) of protein subunits at their polar ends. This would shorten the microtubule and "pull" on it, tugging the chromosome half towards that pole.
WebNov 29, 2024 · During both cell divisions that occur in meiosis, the cell undergoes prophase, metaphase, anaphase, and telophase before the division of the cytoplasm. Though the cell completes PMAT twice,... WebDuring anaphase A, the chromosomes move to the poles and kinetochore fiber microtubules shorten; during anaphase B, the spindle poles move apart as interpolar microtubules elongate and slide past one another. Many cells undergo both anaphase A and B motions, but in some cases one or the other motion dominates.
