Q

What are the 4 phases of mitosis

A

Prophase (two new centriole pairs move to opposite ends of the cell)

Metaphase (chromosomes align near the middle portion between the centrioles, and spindle fibers attach to them)

Anaphase (centromere secretions of each chromosomes, and move toward opposite ends of the cell)(cytokinesis begins here)
