Key differences, features, and comparative analysis of Stage and Key events.
| Stage | Key events |
|---|---|
| Prophase | Chromatin condenses into compact chromosomes (each = 2 chromatids at a centromere); centrosome (with 2 centrioles) has duplicated and the two move to opposite poles, initiating spindle formation; nuclear envelope, nucleolus, Golgi and ER disappear. |
| Metaphase | Chromosomes are most condensed and align at the metaphase plate (equator); spindle fibres attach to the kinetochores on the centromeres. |
| Anaphase | Centromeres split, sister chromatids separate and move as daughter chromosomes toward opposite poles (centromere leading, arms trailing). |
| Telophase | Chromosomes reach the poles and decondense; nuclear envelope, nucleolus, Golgi and ER reappear; two daughter nuclei form. |
