WebSep 5, 2024 · The chromosomes thicken, and then they detach from the nuclear envelope. The centrioles move away from each other and start migrating to opposite sides or poles of the cell. The nucleoli and the … WebThe centrosomes/centrioles move to opposite poles of the cell. And just visible under a light microscope, the sister chromatids are coiled more tightly. Their movement is the important event during cell division. Figure 3. During prometaphase, mitotic spindle microtubules from opposite poles attach to each sister chromatid at the kinetochore.
