The chemical division process called mitosis is split into the following 6 steps, such that: interphase, prophase, metaphase, anaphase, telophase, cytokinasis.

The firts step of mitosis is characterized by the presence of one cell, but in the end of process there exists two identical cells.

The 6 steps of division process mitosis needs the energy stored in cell for the entire process to be completed.

In the first phase of the process, interphase, the DNA replication occurs but DNA molecules are still protected by the nuclear membrane.

In the second phase of the process, prophase, the nuclear membrane is no longer present and the DNA molecules start forming chromosomes.

In the third phase, metaphase, the chromosomes are aligned at the equatorial plate.

In the fourth phase, anaphase, the centromers of chromosomes start to split.

In the fifth phase, telophase, there exists two separate chromosomes.

In the last phase of the process, cytokinasis, there exists two identical cells that contain the same number of chromosomes.

The development of an individual from zygote to adult stage takes place through mitotic cell division. The mitotic phase consists of the following stages:

1) Prophase: At prophase (after DNA synthesis is already completed during interphase), the cell is still preparing for division.

2) Metaphase: At the prophase or early metaphase, the spindle tubules start appearing.

3) Anaphase: After the spindle is formed and the chromosomes have arranged on the equatorial plate, the chromosomes split at the position of centromere also.

4) Telophase: After the anaphase chromosomes have reached the poles, the nuclear membrane is reconstructed around each group of chromosomes giving rise to one nucleus at each pole.
