Mitosis

__** Mitosis **__: is the cell division in eukaryotic cells. Cells divide for growth and repair.**﻿** [|Click her to see an animation on how the cell cycle works]
 * Mitosis **
 * The cell cycle**: is broken down into two stages interphase and M phase. Then interphase is then divided into G1, S, and G2, while M phase is broken down into mitosis and cytokinesis. Then mitosis is divided into prophase, metaphase, anaphase, and telophase.


 * Stages of Mitosis**: There are six phases that happen thoughout mitosis, they are interphase, prophase, metaphase, anaphase, telophase, and cytokinesis.
 * **Interphase**: The first phase in mitosis. During interphase the cell grows, carries out normal cell functions, replicates DNA, and prepares for cell division.
 * **Prophase**: The second stage in mitosis. During prophase chromatin condense into chromosomes, the nuclear envelope disappears, the centrioles separate, and the spindle fibers begin to form.
 * **Metaphase**: The third stage in mitosis. During metaphase the centrioles have reached the opposite sides of the cell, chromosomes line up along the middle of the cell, and each chromosome is connected to a spindle fiber at it centriole.
 * **Anaphase**: The fourth stage of mitosis. During anaphase sister chromatids separate into individual chromosomes and sister chromatids are pulled towards the opposite sides of the cell.
 * **Telophase**: The fifth stage of mitosis. During telophase chromosomes gather at opposite ends of the cell, organized chromosomes become organized chromatin, and two nuclear envelopes form.
 * **Cytokinesis**: The final stage in mitosis. During cytokinesis the cytoplasm and cell membrane pinch in half and each daughter cell produced has an identical set of chromosomes.
 * Cytokinesis differ's between animal and plant cells because plant cells have a rigid cell wall.

 * Cancer**: Cancer is a disorder in which some of the body's own cells lose the ability to control growth. This is called uncontrolled cell growth. There is no one cure for cancer because there are so many different types. Cancer is caused by the cell's not dividing properly and the way mutations occur. Also it is when normal cells begin dividing uncontroably and start pushing beyond their usual boundaries. Cancer isn't just one disease but many.
