What Are the Stages of Mitosis?

The stages of mitosis are prophase, prometaphase, metaphase, anaphase and telekinesis. Mitosis is a biological activity essential for reproduction. In this series of stages, it involves the duplication and division of chromosomes into different groups.

The process of mitosis begins with the prophase. In this phase, chromosomes replicate then shrink, taking the shape of coils. Chromosomes remain in their outer shells, called nuclear envelopes. These envelopes provide nourishment for the chromosomes and offer them protection. Even within the prophase stage, chromosomes undergo dramatic changes from start to finish. They develop more complex features, including a spindle, by the end of prophase. The disintegration of the nuclear envelope ends the prophase stage and triggers prometaphase. This stage involves the movement of chromosome centromeres from the middle of the chromosome to the outer metaphase plate. Congressional movement and the reorganization of chromosomes helps genomes divide easily into two equal parts.

During metaphase, chromosomal changes continue. Chromatid arms, which hold chromosomes together, eventually loosen and split. This split, which occurs at the centromeres, produces two identical daughter cells. The anaphase begins with the daughter cells replicating, producing two identical chromosomes. Lastly, during telekinesis, offspring cells move away from each other. Walls develop between them, physically separating the cells and creating a larger network.
