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. WebExpert Answer Ans: The beginning of anaphase is marked by the separation of centromere and the detachment of sister chromatids from each other.

Do microtubules elongate or shorten during anaphase?

WebThe kinetochore microtubules shorten by depolymerization at their plus ends, and motor proteins associated with the kinetochores keep the chromatids linked to the shortened plus ends, retaining the attachment of the chromatids to the kinetochore microtubules.

WebDuring anaphase of mitosis, the sister chromatids separate and move towards opposite poles of the cell. This movement is facilitated by the shortening of microtubules that are attached to the kinetochore, a structure located at the centromere of each chromatid. When the microtubules shorten, they pull the chromatids apart, marking the beginning ... WebDuring 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. The pulling will also cause the cell to elongate as the sister chromatids are pulled to opposite sides of the cell in preparation to ...

WebFeb 21, 2024 · Anaphase starts after the cell passes the spindle formation checkpoint, which allows chromosomes or chromatids to separate.
