  • M phase is known as mitotic phase and cell division occurs in this phase .

  • The re-formation of the nuclear envelope during M-phase of the cell cycle takes place during telophase .

  • The nuclear membrane which disappears during propahse reappears in the telophase .

  • But before it is reformed the nucleus gets reorganised by Decondensation from chromosomes and reassembly of the nuclear lamina .

______________

⚡ At telophase stage, nuclear membrane vesicles associate with the surface of individual chromosomes and fuse to reform the nuclear membranes, which partially enclose clusters of chromosomes before coalescing to reform the complete nuclear envelope .
