Begin by understanding the process of mitosis, which is the division of a single cell into two genetically identical daughter cells. Mitosis consists of several stages: prophase, metaphase, anaphase, and telophase.
In prophase, the chromatin condenses into visible chromosomes, and the mitotic spindle begins to form. The nuclear envelope starts to break down.
During metaphase, the chromosomes align at the cell's equatorial plane, known as the metaphase plate. The spindle fibers attach to the centromeres of the chromosomes.
Anaphase is the stage where the sister chromatids are separated. The spindle fibers shorten, pulling the chromatids apart toward opposite poles of the cell. This separation ensures that each new cell will receive an identical set of chromosomes.
Finally, in telophase, the separated chromatids reach the opposite poles, and the nuclear envelope re-forms around each set of chromosomes, completing the division of the nucleus.
