Detailed explanation-1: -Mitosis ends with telophase, or the stage at which the chromosomes reach the poles. The nuclear membrane then reforms, and the chromosomes begin to decondense into their interphase conformations.

Detailed explanation-2: -Telophase is the fifth and final phase of mitosis, the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells. Telophase begins once the replicated, paired chromosomes have been separated and pulled to opposite sides, or poles, of the cell.

Detailed explanation-3: -Telophase. In this final stage of mitosis, a nuclear envelope forms around each group of chromosomes and cytokinesis occurs, where the cytoplasm divides into two. The spindle completely disappears and chromosomes undergo the reversal of condensation, deeming them no longer visible under the light microscope.

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: -The chromosome is not visible if the cell is not under the division stage. The telophase is the last stage of mitosis where the chromosomes start decondensation. This results in the chromosomes not being visible under a microscope. Hence, telophase is the stage of mitosis where the chromosomes become invisible.
