Verified step by step guidance1
Understand the process of mitosis, which is divided into several phases: prophase, metaphase, anaphase, and telophase.
Recall that during prophase, the nuclear envelope begins to break down, allowing the chromosomes to condense and become visible.
In metaphase, the chromosomes align at the metaphase plate, but the nuclear envelope is not re-formed at this stage.
During anaphase, the sister chromatids are pulled apart to opposite poles of the cell, and the nuclear envelope is still absent.
Finally, in telophase, the nuclear envelope re-forms around each set of separated sister chromatids, completing the process of mitosis.
