Telophase

Definition

Telophase is the final stage of mitosis where the chromosomes arrive at opposite poles of the cell and begin to decondense. It is followed by cytokinesis, completing cell division and forming two daughter cells.

5 Must Know Facts For Your Next Test

1. During telophase, the nuclear envelope re-forms around each set of chromosomes.
2. Chromosomes decondense back into chromatin in telophase.
3. The mitotic spindle breaks down during telophase.
4. Telophase ensures that each daughter cell receives a complete set of chromosomes.
5. Cytokinesis often begins during telophase, leading to the physical separation of the cytoplasm.

Metaphase: The stage of mitosis where chromosomes align at the metaphase plate, equidistant between the two spindle poles.

Anaphase:
