Mitosis Mitosis is the process by which one parent cell splits into two identical daughter cells. Mitosis is the most common method of reproduction for single-celled organisms. There are 5 main stages of mitosis: Prophase: number of chromosomes in the cell double up Metaphase: chromosomes wind up and align along the equator of the cells Anaphase: Chromatids (Not Chromosomes, this is explained later) are drawn towards the ends of the cell by spindle fibers Telophase: Cell nuclei forms, chromosomes form and unwind Cytokinesis: Cell splits into two, completing the process of mitosis In the human body, all cells other than sex cells (sperm and ova) are generated through mitosis.
