Abstract
The cell cycle is made up of five steps. These steps are interphase, mitosis, cytoplasmic division, cell differentiation, and cell death. During mitosis there is a series of four stages.

The Cell Cycle To start the cell cycle the cells first go through a step called interphase. During this step the cell grows and synthesizes new molecules and organelles. In the S phase the DNA of the cell is replicated in preparation for cell division. It also goes through the G1 and G2 phases that the cell grows and other structures are duplicated.

Mitosis is the next stage where the carefully orchestrated division of the nucleus of the cell that results in each daughter cell receiving an exact copy of the mothers cells genetic material. Inside of the mitosis stage there is four phases Prophase, Metaphase, anaphase, and telophase. In the Prophase phase each duplicated chromosome is seen as a pair of sister chromatids joined by the duplicated but unseparated centromere. The next phase is Metaphase occurs as spindle fibers attach to centromeres on the chromosomes and they align midway between centrioles.

In the anaphase phase the spindle fibers contract and pull sister chromatids toward centrioles. The last phase is telophase. In this phase the chromosomes have completed their migration, the nuclear envelope reappears, and the chromosomes begin to unwind. ("Mitosis: Prophase." Mitosis: Prophase. N.p., n.d.

During the Cytoplasmic division cytokinesis begins during anaphase of mitosis and continues as a contractile ring punches the two new cells apart. The two daughter cells may have varying amounts of cytoplasm and organelles, but they share identical genetic
