Verified step by step guidance

Understand the process of mitosis: Mitosis is the division of a cell's nucleus into two genetically identical nuclei. It consists of several phases: prophase, metaphase, anaphase, and telophase.
Recall the key events of metaphase: During metaphase, chromosomes align at the cell's equatorial plate (also called the metaphase plate). This alignment ensures that each daughter cell will receive an identical set of chromosomes.
Compare metaphase to other phases: In prophase, chromosomes condense and the nuclear envelope breaks down. In anaphase, sister chromatids are pulled apart to opposite poles of the cell. In telophase, the nuclear envelope reforms around the separated chromatids.
Identify the phase where chromosomes align at the equatorial plate: Based on the description, this event is characteristic of metaphase.
Conclude that the correct answer is metaphase, as it is the phase where chromosomes align at the cell's equatorial plate, ensuring proper segregation during cell division.
