It is a type of cell division whereby the cell undergoes division
The most important stage in mitosis can be referred to as metaphase.
Metaphase:
In metaphase chromosomes are most compact in metaphase when the centromeres of the chromosomes of all cells are aligned with the equator of the mitotic spindle.
Chromosomes are most easily visualized at this stage, so metaphase is especially useful in cytogenetics.
In addition, cells can be experimentally arrested in metaphase with mitotic toxins such as colchicine.
