What occurs during telophase of mitosis?

During telophase of mitosis, a significant event is the reformation of the nuclear envelope around the separated sets of chromosomes. This process marks the final stage of mitosis, where the chromosomes, having been pulled to opposite ends of the cell during anaphase, begin to de-condense back into a less tightly coiled state. The nuclear materials reform, leading to the establishment of two distinct nuclei within the cell.

This reformation is critical because it signifies the near completion of the cell division process, setting the stage for the final physical separation of the cell itself, known as cytokinesis. The correct understanding of telophase is that it is characterized by this reconstitution of the nuclei, allowing the genetic material to be housed appropriately in each new cell that will emerge from the division process.
