WebAug 7, 2024 · Anaphase: During anaphase, the centromere splits, allowing the sister chromatids to separate. The kinetochore spindle fibers shorten, allowing for 46 of the newly- freed chromatids to be dragged to one end of the cell and the remaining 46 chromatids to be dragged to the opposite end of the cell.

WebMay 5, 2000 · Microtubule sweeping and capture/shrinkage during anaphase spindle movements in ts-arp1 cells. (A) In this cell, microtubules do not make lateral associations with the bud cortex and do not slide but do sweep. The spindle does not move into the neck. Later a microtubule grows very long and buckles as the spindle is pushed out of the neck. 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. howden health and benefits
