Verified step by step guidance

Understand the context of the problem: Mitosis is a process of cell division that results in two genetically identical daughter cells. It consists of several phases: prophase, metaphase, anaphase, and telophase.

Recall the events of telophase: During telophase, the chromosomes that have been separated move to opposite ends of the cell, and the cell begins to return to its normal state.

Identify the structures involved: In telophase, the nuclear envelope, which had disintegrated during prophase, begins to re-form around each set of separated sister chromatids, now individual chromosomes.

Differentiate between the structures: Chromatids are the duplicated chromosomes that separate during mitosis. Spindle fibers are structures that help in the movement of chromosomes. Centromeres are the part of a chromosome that links sister chromatids.

Conclude which structure reappears: The nuclear envelope reappears during telophase, enclosing the chromosomes in the newly forming nuclei of the daughter cells.
