Telophase
The final stage of karyokinesis where chromosomes decondense and nuclear envelopes reform around the two sets of chromosomes.
What is Telophase?
The division of the nucleus.
Key points
- Identify telophase as the final stage of nuclear division.
- Describe the key events occurring during telophase.
- Differentiate telophase from other stages of mitosis and meiosis.
- Explain the role of telophase in the formation of daughter nuclei.
Common exam trap
Confusing telophase with cytokinesis.

Prerequisites
Understanding of mitosis and meiosis.
Knowledge of chromosome structure and behavior.
Familiarity with spindle fibers and nuclear envelope.
Basic understanding of cell cycle stages (Prophase, Metaphase, Anaphase).
Common mistakes
Confusing telophase with cytokinesis.
Forgetting that chromosomes decondense.
Not recognizing that nuclear envelopes reform.
