Comment on the statement- Telophase is reverse of prophase.
During telophase, events of prophase occur in reverse sequence. Prophase is known for the initiation of condensation of chromosomal material, which during the process of chromatin condensation becomes untangled, and finally, the centriole (already duplicated during S-phase of interphase) begins to move towards the opposite pole of the cell. In this phase, initiation of mitotic spindle assembly, microtubular and proteinaceous components of cell cytoplasm help in the completion of the process.
At the end of the prophase, i.e., during late prophase, the nucleolus disintegrates gradually and the nuclear envelope disappears. This disappearance marks the end of the prophase.
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. The chromosomes gradually uncoil and cluster at opposite spindle poles thus, their individual identity as discrete elements is lost. Nuclear envelope slowly reforms around each group of chromosomes and nucleolus, Golgi complex and ER reappears.
