Sure! The metaphase stage in the cel is the third step in mitosis. The chromosomes line up in the middle of the cell due to the fact that the spindle fibers pull them towards the middle (the chromosomes are in a single file line). In addition, the spindle fibers connect to the centromeres. Hope this helps :)
Thank you so much for the points luv ya
