Detailed explanation-1: -During cytokinesis, the cell membrane pinches in at the cell equator, forming a cleft called the cleavage furrow.

Detailed explanation-2: -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-3: -Finally, once anaphase is complete, the cell enters the last stage of the division process-telophase. 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-4: -In telophase, the cell is nearly done dividing, and it starts to re-establish its normal structures as cytokinesis (division of the cell contents) takes place. The mitotic spindle is broken down into its building blocks. Two new nuclei form, one for each set of chromosomes. Nuclear membranes and nucleoli reappear.
