Mitosis is a type of cell division in which one parent cell divides into two genetically identical daughter cells. 

The daughter cells produced are diploid. Diploid is a term given to cells which have two sets of chromosomes.

Mitosis is the cell division which occurs for all our body cell except gametes. Gametes are produced by meiosis.

Phases of Mitosis

  • Prophase
  • Metaphase
  • Anaphase
  • Telophase

Interphase occurs before the actual process of mitosis. 


Interphase
Interphase is the phase of the cell cycle in which the cell copies its DNA in preparation for the cell division. 

The cell organelles double in number, the DNA replicates and protein synthesis occurs. 
The chromosomes are not visible and the DNA appears as uncoiled chromatin.

Prophase
During prophase, chromosomes begin to condense. 
The spindle forms and the microtubules begin to attach to chromosomes. 

The two sister chromatids of each chromosome attach to opposite spindles. 

Metaphase
The chromosomes line up individually along the equator. 

Anaphase
The sister chromatids separate and are pulled towards the opposite poles. 

Telophase
The spindle breaks down.
The chromosomes decondense and the nuclear membrane reforms. 

Cytokinesis
This is the division of cytoplasm to form two new cells. In animals, cytokinesis is contractile. 

When cytokinesis finishes, we end up with two new cells, each with a complete set of chromosomes. These cells are identical to the parent cell.
