Answer:
1. Nuclear membrane and nucleolus disappear: Prometaphase.
2. Spindle is formed: Prophase
3. Separation of sister chromatids: Anaphase
4. Daughter cells are usually formed: Telophase
5. Rod-shaped chromosomes are first visible: Prophase (first visible) Metaphase (completely visible).
6. Chromosomes line up on equatorial plane: Metaphase
7. New nuclei are formed: Telophase
8. Daughter chromosomes migrate to opposite poles of the cell: Anaphase
Explanation:
Mitosis process occurs in the following order:
1. Prophase: Prophase is the start of cellular division. In this step, chromatin is condensed into chromosomes and spindle is formed.
2. Prometaphase: In this step, the nuclear membrane breaks down and sister chromatids start to migrate to the equator of the cell.
3. Metaphase: Here, chromatids are aligned into the cell's equator and now chromosomes has the rod-shape.
4. Anaphase: Sister chromatids separate, and they migrate toward the daughter cells' poles.
5. Telophase: Here, new nuclear membranes are formed and daughter cells can be seen. Finally, they separate into two new cells.
