This is a retouched picture, which means that it has been digitally altered from its original version. Modifications: changed to better represent duration of cell cycle phases. The original can be viewed here: Cell Cycle 2.svg. Modifications made by Histidine.

Original figure:

Description English: The four phases of the cell cycle. G1 - the intitial growth phase. S - the phase in which DNA is synthesised. G2 - the second growth phase in preparation for cell division. M - mitosis; where the cell divides to produce two daughter cells that continue the cell cycle.

Description English: A diagram of mitosis stages
Interphase (G₂): In this substage, the cell prepares for nuclear division and a protein that makes microtubles for cell division is synthesized.
Prophase: The longest stage of mitosis. In this stage the chromosomes become visible and the centrioles separate and move to opposite poles of the cell.
Prometaphase: The nuclear envelope disintegrates and microtubules can attach to kinetochores. Chromosomes congress toward the metaphase plate of the cell.
Metaphase: In this stage the chromosomes line up across the center of the cell and become connected to the spindle fiber at their centromere.
Anaphase: In this stage the sister chromatids separate into individual chromosomes and are pulled apart.
Telophase & cytokinesis: Chromosomes decondense and are surrounded by a newly formed nuclear envelope. Cytokinesis typically coincides with and telophase.
