Modelling Mitosis

Interphase – In this stage, the cell is preparing itself for division, so the DNA is being copied, and the cell is growing as well.

Prophase – In prophase, the nucleus disappears, and centrosomes start to advance towards the opposite poles. Spindle fibres also appear in this stage, and start to form the mitotic spindle.

Metaphase – The spindle fibres form the mitotic spindle in the centre of the cell, and centrosomes appear at the opposite poles of the cell.  Sister chromatids are attached to a spindle fibre on the opposite poles as well.

Anaphase – In anaphase, the chromosomes are attracted to the opposite poles and the poles are moving farther apart.

Telophase – Lastly, the chromosomes reach the opposite poles and the mitotic spindle is broken up. The cell goes through cytokinesis in this stage as well, and the daughter cells become two separate cells.
