The mitotic spindle also begins to develop during prophase. As the cell's two centrosomes move toward opposite poles, microtubules gradually assemble between them, forming the network that will later pull the duplicated chromosomes apart.
Also question is, what is the function of microtubules during mitosis?
A notable structure composed largely of microtubules is the mitotic spindle, used by eukaryotic cells to segregate their chromosomes during cell division. The mitotic spindle includes the spindle microtubules, microtubule-associated proteins (MAPs), and the MTOC.
What are the 4 functions of microtubules?
Other than support, organelle movement, and cell division, microtubules also play a part in forming large structures on the outside of the cells. Microtubules can combine in very specific bundles to form cilia and flagella for cell movement.
What do aster microtubules do?
Chromosomes are attached to kinetochore microtubules via a multiprotein complex called the kinetochore. Polar microtubules interdigitate at the spindle midzone and push the spindle poles apart via motor proteins. Astral microtubules anchor the spindle poles to the cell membrane.
