Detailed explanation-1: -During telophase, the chromosomes continue to decondense, the spindle disintegrates, and the nuclear membranes and nucleoli re-form. Telophase begins as anaphase comes to an end. During anaphase, the chromosomes or chromatids on the metaphase plate are split and driven towards opposing poles.

Detailed explanation-2: -During telophase both sets of chromatids are surround by new nuclear membranes and chromosomes decondense into chromatin. Cytokinesis (the dividing of the cytoplasm into two cells) follows telophase. If the cell were arrested during telophase, distinct chromatids would no longer be visible.

Detailed explanation-3: -Telophase I: The chromosomes are now at opposite ends of the cell and begin to form two distinct chromosome clusters. At this point, nuclear division begins, and the parent cell is divided in half, forming 2 daughter cells. Each daughter cell will have half of the original 46 chromosomes, or 23 chromosomes.

Detailed explanation-4: -During telophase, the nuclear envelope reforms on the surface of the separated sister chromatids, which typically cluster in a dense mass near the spindle poles (Fig. 44.18).
