Verified step by step guidance

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 phases: prophase, metaphase, anaphase, and telophase.

In prophase, the chromosomes condense and become visible. The nuclear envelope begins to break down, and the mitotic spindle starts to form.

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 phase where the sister chromatids are separated and pulled apart toward opposite poles of the cell. This is facilitated by the shortening of the spindle fibers attached to the chromatids.

Finally, in telophase, the separated chromatids reach the opposite poles, and the nuclear envelope re-forms around each set of chromosomes, completing the division process.
