The mitotic phase is a multistage process during which the duplicated chromosomes are aligned, separated, and moved to opposite poles of the cell, and then the cell is divided into two new identical daughter cells.

The first portion of the mitotic phase, mitosis, is composed of five stages which includes prophase, prometaphase, metaphase, anaphase, telophase , which accomplish nuclear division before reaching the second stage which is cytokinensis which involves the physical separation of the cytoplasmic componenets into two daughter cells.
