Final answer:
Mitosis is divided into five stages: prophase, prometaphase, metaphase, anaphase, and telophase. These stages ensure the proper division of the cell nucleus.
Step-by-step explanation:
Mitosis is divided into five stages:
- Prophase: In prophase, chromatin condenses into chromosomes, and the nuclear envelope breaks down.
- Prometaphase: During prometaphase, the spindle forms and attaches to the chromosomes.
- Metaphase: Metaphase is when the chromosomes line up in the middle of the cell.
- Anaphase: Anaphase is when the sister chromatids separate and move to opposite ends of the cell.
- Telophase: Telophase is when the nuclear envelope reforms and the chromosomes begin to unwind.
These stages of mitosis ensure the proper division of the cell nucleus.
