Metaphase
|

Anaphase
|
|
|
Telophase
|
Explanation:
Detailed explanation-1: -During telophase, the nuclear envelope begins to re-form around the divided chromatids.
Detailed explanation-2: -During telophase, the chromosomes arrive at the cell poles, the mitotic spindle disassembles, and the vesicles that contain fragments of the original nuclear membrane assemble around the two sets of chromosomes.
Detailed explanation-3: -During telophase, the nuclear envelopes reform around the new nuclei in each half of the dividing cell. The nucleolus, or ribosome producing portions of the nucleus return. As the cell has finished moving the chromosomes, the main parts of the spindle apparatus fall depolymerize, or fall apart.
