Detailed explanation-1: -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-2: -The nuclear membrane develops in telophase of the cell division. Telophase is the last stage of cell division in which envelope around the nucleus is formed, chromosomes become long, and chromatin fibers, spindle fibers and astral rays disappear. This phase is followed by cytokinesis.

Detailed explanation-3: -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-4: -The nucleolus and the nuclear membrane reappear and the nucleus revert to the interphasic condition with the chromatin appearing as delicate threads. The nuclear membrane reforms from fragments of the parent cell’s nuclear envelope as well as other portions of the inracellular membranes.

Detailed explanation-5: -In addition, the cytoplasmic network of microtubules begins to once again define the cellular structure. The nuclear membrane is reassembled during late telophase from vesicles that surround individual chromosomes, which eventually fuse into larger groups that finally associate to complete the structure.
