mitosis
Splitting of replicated chromosomes, and the division of the cytoplasm to produce two genetically identical daughter cells.

Mitosis is when one animal or plant cell creates two identical copies of itself by splitting in half. Before mitosis, the cell creates an identical set of genetic information - this is called "DNA replication". The duplicated genetic information then winds up into a visible object called a chromosome. A chromosome is made up of two chromatids joined at the centromere.
Mitosis happens in all types of cells in the human body apart from three types: sperm, ova, and neurons. The sex cells (sperm and ova (also called gametes)) go through a different division method called meiosis and neurons do not ever divide.
Phases of Mitosis.
There are six phases of mitosis. Each phase is used to describe what kind of change the cell is going through. The phases are Interphase, Prophase, Metaphase, Anaphase, Telophase, and Cytokinesis. Some may consider Pro-metaphase as part of the phases but most believe it is part of metaphase and some of the end of prophase. Each phase is important to mitosis.
Prophase.
During prophase, the cell's genetic material (DNA), or deoxyribonucleic acid, along with ribonucleic acid (RNA), coils up into bunches called chromosomes. The genetic material has already been duplicated during interphase, so there are double the amount of chromosomes in a normal cell in it. For example, a human cell normally has 23 pairs of chromosomes, but during early mitosis there are 46 pairs.
Metaphase.
During metaphase, the chromosomes are pulled by microtubules called spindle fibers
