Detailed explanation-1: -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.

Detailed explanation-2: -Telophase. The spindle disappears, a nuclear membrane re-forms around each set of chromosomes, and a nucleolus reappears in each new nucleus.

Detailed explanation-3: -During telophase, a nuclear membrane forms around each set of chromosomes to separate the nuclear DNA from the cytoplasm.

Detailed explanation-4: -During the telophase of the cell cycle, karyokinesis (splitting of the nucleoplasm and formation of two distinct nuclei) and cytokinesis occur (formation of two cells by the division of the cytoplasm) takes place. The nuclear envelope reappears around each set of chromosomes during the telophase of the cell cycle.
