MITOSIS

A detailed Summary of MITOSIS


Mitosis is the process of nuclear division in a living cell by which the chromosomes are exactly replicated, the two parts being separated are given to the daughter nuclei. In this process the two daughter cells receive chromosomes that are alike in composition and equal in the number of chromosomes as the parent cell. Mitosis consists of four main stages. Mitotic division occurs in somatic (body) cells. The stages are prophase, metaphase, anaphase, and telophase.

In interphase the cell seems to be inactive for most of the time. Really the cell is undergoing normal cell processes, and all metabolic activities. Towards the end interphase the cell undergoes preparations for cell division, yet sometimes in this stage the chromosome duplicate. Interphase consists of three stages: Growth one, S phase (DNA


The last phase of mitosis is telophase. The chromosomes move and gather around close to the spindle pole region, and the spindle midzone starts to clear. The cytoplasm is divided between the eventually new cells. In the middle of the spindle region a thin line of vesicles starts to form. In plants the cell wall is formed. Then cytokinesis starts, the line forms the new cell membrane.

Now two totally functional cells have been formed. Both cells are genetically identical. Mitosis is happening all the time, in fact it happens 25 million times a second in the human body. Mitosis brings meaning to the cell theory, “All cells are the units of structure and function in living organisms / And all new cells come from cells that already exist.” Mitosis is vital for growth, repair and replacement of damaged or wo
