Verified step by step guidance

Understand the stages of mitosis: Mitosis is divided into several stages: prophase, prometaphase, metaphase, anaphase, and telophase.

Recall the key events in each stage: During prophase, the chromatin condenses into chromosomes. In prometaphase, the nuclear envelope breaks down. Metaphase is characterized by chromosomes aligning at the metaphase plate. Anaphase involves the separation of sister chromatids.

Focus on telophase: In telophase, the chromosomes arrive at opposite poles of the cell. This is the stage where the nuclear envelope begins to reform around each set of chromosomes.

Connect the event to the stage: Since the nuclear envelope reforms during telophase, this is the stage you are looking for in the context of the problem.

Review the sequence of events: Ensure you understand the sequence of mitotic events and how the reformation of the nuclear envelope fits into the overall process of cell division.
