During anaphase where do microtubules shorten

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. WebAnaphase . During anaphase the microtubules shorten so much that the sister chromatids start to pull apart. The chromatids can only come apart if the proteins that are linking them together (cohesion proteins) are cleaved.
