Detailed explanation-1: -During the completion of mitosis (telophase), two new nuclei form around the separated sets of daughter chromosomes (see Figure 8.29).

Detailed explanation-2: -The telophase stage is marked by the appearance of new nuclear membranes. This is the end of mitosis. Finally, the splitting of the cell occurs during cytokinesis. The two new cells are now ready to grow and perform their specialized functions.

Detailed explanation-3: -During telophase, a nuclear membrane forms around each set of chromosomes to separate the nuclear DNA from the cytoplasm. The chromosomes begin to uncoil, which makes them diffuse and less compact.

Detailed explanation-4: -In telophase I, the microtubules break down, the nuclear membrane reforms, and the chromosomes return to an uncondensed state. The cell then divides into two haploid daughter cells by cytokinesis.

Detailed explanation-5: -What Happens during Telophase? During telophase, the chromosomes arrive at the cell poles, the mitotic spindle disassembles, and the vesicles that contain fragments of the original nuclear membrane assemble around the two sets of chromosomes. Phosphatases then dephosphorylate the lamins at each end of the cell.
