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: -During the completion of mitosis (telophase), two new nuclei form around the separated sets of daughter chromosomes (see Figure 8.29).
Detailed explanation-3: -Telophase is a phase of both mitosis and meiosis. In telophase, a new nuclear membrane forms around each of the set of freshly separated chromosomes which have just reached the mitotic spindle on opposite ends of the cell in mitosis.
Detailed explanation-4: -During telophase, the chromosomes begin to decondense, the spindle breaks down, and the nuclear membranes and nucleoli re-form. The cytoplasm of the mother cell divides to form two daughter cells, each containing the same number and kind of chromosomes as the mother cell.
Detailed explanation-5: -The last stage of Meiosis I is telophase I. 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.
