1. Interphase
2. Prophase
3. Metaphase
4. Anaphase
5. Telophase
6. Cytokinesis
7. DNA replication occurs during interphase.
8. Chromosomes condense and become visible; the nuclear envelope breaks down.
9. Chromosomes line up at the equator (metaphase plate) of the cell.
10. Sister chromatids separate and are pulled to opposite poles of the cell.
11. Nuclear envelopes reform around each set of chromosomes; chromosomes decondense.
12. The cytoplasm divides, forming two daughter cells.
13. A cell in telophase is completing division; a cell in interphase is preparing for division.
14. The cell cycle is regulated by checkpoints that ensure each phase is completed correctly before proceeding.
15. Mitosis ensures each daughter cell receives an identical copy of the parent cell's chromosomes.
16. Cytokinesis is the division of the cytoplasm, which follows mitosis.
17. A cell in early prophase has condensed chromosomes but no spindle fibers yet; a cell in late prophase has spindle fibers attached to chromosomes.
18. During cytokinesis in animal cells, a cleavage furrow forms; in plant cells, a cell plate forms.
19. The cell cycle is tightly regulated to prevent uncontrolled cell division, which can lead to cancer.
20. Cells spend most of their time in interphase, preparing for division.
