So basically, in ProPhase one, our centrioles begin to move to opposite ends. And as they move to opposite ends, they begin to form our spindle apparatus, our spinal fibers that extend towards our chromosome, as shown in the following diagram. So let's move on to metaphase two. In metaphase II, the spindle fibers formed from our centrioles, which are now found on opposite ends of the cell, basically grab our chromosome as a kinetic core region on the centromere. And that is shown in the following diagram. And once they grab it, they align the chromosomes at the center of the cell at our equator, as shown in the following diagram.
