During anaphase where do microtubules shorten
WebAnaphase. The sister chromatids separate from one another and are pulled towards opposite poles of the cell.

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. The pulling will also cause the cell to elongate as the sister chromatids are pulled to opposite sides of the cell in

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. It would have no effect.
WebDuring anaphase, the sister chromatids are separated and pulled towards opposite poles of the cell by the shortening of the chromosomal microtubules.
