WebTelophase: The final stage of mitosis is telophase. The spindle apparatus breaks down, and the chromosomes begin to unwind back into chromatin. The nuclear envelope reforms around each set of chromosomes, creating two new nuclei. Finally, the cell undergoes cytokinesis, where the cytoplasm divides, forming two identical daughter cells.
