Multiple forces act on chromosomes in the spindle, except?

#Unit 2. Cellular Organization
  1. A force pulls the kinetochore and its associated chromatid along the kinetochore microtubule toward the spindle pole.
  2. A poleward force is provided in some cell types by microtubule flux, whereby the microtubules themselves are pulled toward the spindle poles and dismantled at their minus ends.
  3. A force acting on chromosomes is the polar ejection force, or polar wind.
  4. A force that remove cohesin from the chromosome arms.
