Answer;
-Telophase
Explanation;
-The spindle apparatus disintegrates during the telophase of mitosis. Telophase is the final stage of mitosis.
-During this phase, the sister chromatids reach opposite poles. The small nuclear vesicles in the cell begin to re-form around the group of chromosomes at each end.
-As the nuclear envelope re-forms by associating with the chromosomes, two nuclei are created in the one cell. Telophase is also marked by the dissolution of the kinetochore microtubules and the continued elongation of the polar microtubules.
