BRAINCAKETelophase
Telophase is the final stage of mitosis. It begins when the separated chromatids, now called chromosomes, arrive at opposite poles of the cell at the end of anaphase.
In telophase the events of prophase are essentially reversed:
• a new nuclear envelope forms around each group of chromosomes, giving two nuclei;
• the nucleolus reappears in each new nucleus;
• the chromosomes uncoil and become long, thin chromatin again, so they can no longer be seen with a light microscope;
• the spindle fibres break down.
