Web11 jul. 2024 · The mitotic spindle also starts to develop during the prophase. As the two centrosomes of the cell move toward opposite poles, microtubules gradually collect between them, forming a network that later pulls the duplicated chromosomes apart. Prometaphase Once the prophase is over, the cell enters the second stage for mitosis— prometaphase. Web1 feb. 2024 · Centrosomes in mitotic spindle assembly and orientation. The centrosome is present in most animal cells and functions as the major microtubule-organizing center to ensure faithful chromosome segregation during cell division.
