A four-stage process that creates two identical cells from one original cell.
Prophase
This is the first and longest stage, the chromosomes become visible and the centrioles separate, moving to opposite poles.
Metaphase
In the second stage, the chromosomes line up in the cell, becoming connected to the centromere by the spindle fiber.
Anaphase
In the third stage, the sister chromatids separate into two chromosomes, they have been pulled apart.
Telophase
The final stage of mitosis where the chromosomes gather at opposite ends of the cell, losing the distinct shapes. Two new nuclear membranes form around each of the two regions of DNA, spindle fibers are gone.
