during prophase, the move towards the poles of the cell, and a spindle begins to form between them.
Answer
Brief Explanations:
In cell division (mitosis or meiosis), during prophase, the centrioles (in animal cells) or microtubule - organizing centers move towards the poles of the cell, and the spindle apparatus begins to form between them. This is a key event in the early stages of cell division as the spindle will later be involved in separating the chromosomes.

centrioles (or microtubule - organizing centers)
