Understand that mitosis is the process of cell division where a single cell divides to produce two identical daughter cells. It consists of four main stages: Prophase, Metaphase, Anaphase, and Telophase, which occur in a specific order.
Step 1: Prophase - During this stage, the chromatin condenses into visible chromosomes, the nuclear envelope begins to break down, and the spindle fibers start to form.
Step 2: Metaphase - The chromosomes align at the metaphase plate (the cell's equatorial plane), and spindle fibers attach to the centromeres of the chromosomes.
Step 3: Anaphase - The sister chromatids are pulled apart by the spindle fibers and move toward opposite poles of the cell.
Step 4: Telophase - The chromosomes reach the poles, the nuclear envelope re-forms around each set of chromosomes, and the chromosomes begin to decondense. This is followed by cytokinesis, where the cell physically divides into two daughter cells.
