See mommy everything can be explained by science.
The 4 stage of Mitosis is Telophase. In this phase the nuclear membrane reforms and begins to split into two. These resulting cells will be identical. In this stage the cells are still not completely split.
The final stage of Mitosis is Cytokinesis. During Cytokinesis the cytoplasm fully separates into two creating two identical daughter cells. After this phase the cells go back to Interphase and starts over.
After Little Timmy Panda explained the process of Mitosis to his mommy she calmed down and was relieved that he was not going to die.
