Detailed explanation-1: -During anaphase, sister chromatids are separated at the centromere and are pulled towards opposite poles of the cell by the mitotic spindle. During telophase, chromosomes arrive at opposite poles and unwind (uncoil) into thin strands of DNA, the spindle fibers disappear, and the nuclear membrane reappears.
Detailed explanation-2: -Metaphase leads to anaphase, during which each chromosome’s sister chromatids separate and move to opposite poles of the cell.
Detailed explanation-3: -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-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).
Detailed explanation-5: -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.
