Detailed explanation-1: -During prophase, the cell has a single nucleus and its nuclear envelope disappears. Later the nucleus divides into two. Hence, during telophase, the cell has two newly formed nuclei. A new nuclear envelope develops around the two newly formed nuclei.
Detailed explanation-2: -Telophase, the terminal phase of mitosis, is characterized by cytokinesis, reconstitution of the nucleus and nuclear envelope, disappearance of the mitotic spindle apparatus, and unwinding of the chromosomes into chromatin.
Detailed explanation-3: -The reverse of prophase is the telophase. At the onset of this stage, the spindle disappears (absorbed in cytoplasm) and the chromosomes decondense and further loses their individuality after reaching their respective poles.
Detailed explanation-4: -Telophase of mitosis is essentially the reverse of prophase in terms of nuclear changes.
