Solution
To separate the chromosomes
Explanation:
Spindle fibres, also known as microtubules, emerge from the centrosomes and cling to the centromeres of chromosomes during mitosis. Their main job is to arrange the chromosomes in the metaphase plate. During anaphase, they separate the sister chromatids and draw them to the cell’s poles. This guarantees that the genetic material is distributed equally throughout the daughter cells.
