Detailed explanation-1: -Telophase begins once the replicated, paired chromosomes have been separated and pulled to opposite sides, or poles, of the cell. During telophase, a nuclear membrane forms around each set of chromosomes to separate the nuclear DNA from the cytoplasm.

Detailed explanation-2: -During telophase, the newly separated chromosomes reach the mitotic spindle and a nuclear membrane forms around each set of chromosomes, thus creating two separate nuclei inside the same cell.

Detailed explanation-3: -In the telophase stage (seeFigure 3-14G andH), the two sets of daughter chromosomes are pushed completely apart. Then, the mitotic apparatus dissipates, and a new nuclear membrane develops around each set of chromosomes.

Detailed explanation-4: -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.

Detailed explanation-5: -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.
