During anaphase where do microtubules shorten
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. The pulling will also cause the cell to elongate as the sister chromatids are pulled to opposite sides of the cell in WebAnaphase - an overview ScienceDirect Topics

Spindle fibers not connected to chromatids lengthen and elongate the cell. At the … 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.

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. The overlap microtubules do not shorten, but instead lengthen to push the two poles of the cell apart.

During the first part of anaphase, the kinetochore microtubules shorten, and the chromosomes move toward the spindle poles. During the second part of anaphase, the spindle poles separate as the non-kinetochore microtubules move past each other.
