Detailed explanation-1: -So when the cell is going to divide, those centrioles go to opposite ends of the nucleus. And when the chromosomes are condensing to undergo mitosis, the centrioles form the areas that mitotic spindle forms from.

Detailed explanation-2: -At the end of mitosis, the mitotic spindle segregates the duplicated centriole pairs, so that each resulting daughter cell contains two centrioles.

Detailed explanation-3: -Centrioles begin moving to opposite ends of the cell and fibers extend from the centromeres. Some fibers cross the cell to form the mitotic spindle. The nuclear membrane dissolves, marking the beginning of prometaphase. Proteins attach to the centromeres creating the kinetochores.

Detailed explanation-4: -Centrioles split and move to the opposite ends of the cell at the poles towards the end of Prophase. The moving of centrioles to the poles helps organize the spindle fibres that begin to play a role from the metaphase onwards.

Detailed explanation-5: -During prophase, the spindle also begins to form as the two pairs of centrioles move to opposite poles and microtubules begin to polymerize from the duplicated centrosomes.
