Mitosis is the process by which a eukaryotic cell divides to produce two genetically identical daughter cells. It is essential for growth, tissue repair, and asexual reproduction.
Stages of Mitosis
A common way to remember them is PMAT:
1. Prophase
Chromosomes condense and become visible.
Nuclear membrane breaks down.
Spindle fibers form.
2. Metaphase
Chromosomes line up at the center of the cell (metaphase plate).
3. Anaphase
Sister chromatids separate and move to opposite poles.
4. Telophase
New nuclear membranes form around each set of chromosomes.
Chromosomes begin to uncoil.
After mitosis, the cell usually undergoes cytokinesis, where the cytoplasm divides, forming two separate cells.
