During telophase, the final stage of mitosis, several key events occur:
- Chromosome separation : The chromosomes arrive at the cell poles, ensuring that each daughter cell will contain one exact copy of the parent cell DNA
- Mitotic spindle disassembly : The spindle microtubules break down, as their job is completed
- Nuclear envelope formation : A new nuclear envelope, derived from vesicles of endoplasmic reticulum, surrounds the unraveling chromosomes
- Nucleoli re-formation : Nucleoli re-form in each daughter cell
- Chromosome decondensation : The chromosomes begin to decondense and return to their "stringy" form
- Cytokinesis : The division of the cytoplasm to form two new cells overlaps with the final stages of mitosis
Telophase is the fifth and final phase of mitosis, and it ensures the proper distribution of genetic material to the daughter cells
. Once telophase is complete, the cell undergoes cytokinesis, which divides the cytoplasm into two new cells, each containing a complete set of chromosomes
