The process of mitosis is a series of steps that ensure the equal distribution of duplicated chromosomes into two daughter cells. The correct order of the stages in mitosis is as follows:
1. **Prophase**: Chromatin condenses into visible chromosomes, and the nuclear envelope begins to break down. The mitotic spindle starts to form from the centrosomes.
2. **Prometaphase**: The nuclear envelope completely breaks down. Microtubules from the spindle apparatus attach to the kinetochores of the chromosomes.
3. **Metaphase**: Chromosomes align at the metaphase plate (the cell's equatorial plane). This alignment ensures that each daughter cell will receive one copy of each chromosome.
4. **Anaphase**: The sister chromatids are pulled apart as the spindle fibers shorten, moving them toward opposite poles of the cell.
5. **Telophase**: Chromatids reach the poles and begin to decondense back into chromatin. The nuclear envelope re-forms around each set of chromosomes, resulting in two distinct nuclei.
After mitosis is completed, the cell usually undergoes **cytokinesis**, which is the division of the cytoplasm, resulting in two separate daughter cells.
So, the order is: **Prophase → Prometaphase → Metaphase → Anaphase → Telophase**.
