Telophase is the final stage of mitosis. It begins when the chromosomes reach the opposite poles of the cell.At each pole the chromosomes uncoil and become long, thin, loosely coiled chromatin again, so they are no longer visible under the light microscope.A nuclear envelope reforms around each set of chromosomes and a nucleolus reappears in each new nucleus. In effect, the changes of prophase are reversed.The spindle fibres break down. The result is two genetically identical nuclei within one cell, each with the same number of chromosomes as the parent nucleus.Telophase is followed closely by the division of the cytoplasm, which completes the formation of two daughter cells.
