The protein “glue” that holds the sister chromatids together is broken down, allowing them to separate. Each is …
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 ... 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 …

WebSee Answer Question: The drug taxol stabilizes microtubules so they cannot shorten. If taxol were added during mitosis, what effect would you expect it to have? Spindle fibers would not be able to attach to kinetichore proteins. Daughter chromosomes would not migrate to opposite poles during anaphase.

The movement of chromosomes during anaphase is essential for successful cell division, and it is mediated by a number of cellular processes, including the elongation and shortening of microtubules. csulb health servicesWebDuring 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. early transparent gage
