At the beginning of the final stage of mitosis, i.e., telophase, the chromosomes that have reached their respective poles decondense and lose their individuality.
The individual chromosomes can no longer be seen and chromatin material tends to collect in a mass in the two poles.
This is the stage which shows the following key events:
- Chromosomes cluster at opposite spindle poles and their identity is lost as discrete elements.
- Nuclear envelope assembles around the chromosome clusters. z Nucleolus, golgi complex and ER reform.
