It is a type of nuclear division which gives rise to two genetically identical daughter cell having the same number of chromosomes as the parent cell.
1 of 6
Prophase
Chromosomes become visible due to the coiling of chromatin fibres. The nuclear envelope disintegrates. Centrioles move to opposite poles and start radiating spindle fibres.
2 of 6
Metaphase
The chromatids are attached to the spindle fibres through their centromeres. The spindle fibres contract from both sides and as a result the chromosomes align at the equator.
3 of 6
Anaphase
The centromeres divide into two. The microtubules contract causing individuals chromatids to separate and move to opposite poles.
4 of 6
Telophase
The daughter chromatids reach their respective poles. The spindle fibres disintegrate and the nuclear membrane and nucleolus re form.

Cytokinesis
it is the division of the cytoplasm into two equal parts.
