Telophase (from the Greek τελος meaning "end") is a reversal of prophase and prometaphase events. It "cleans up" the after effects of mitosis. At telophase, the polar microtubules continue to lengthen, elongating the cell even more. Corresponding daughter chromosomes attach at opposite ends of the cell. A new nuclear membrane, using the membrane vesicles of the parent cell's old nuclear membrane, forms around each set of separated daughter chromosomes (though the membrane does not enclose the centrosomes) The nucleoli reappear, too. Both sets of chromosomes, now surrounded by new nuclei, begin to "relax" or decondense back into chromatin. Mitosis is complete, but cell division is not.
