Understand the stages of mitosis: Mitosis is divided into several stages: prophase, metaphase, anaphase, and telophase. Each stage has distinct events that occur.
Identify the key event of metaphase: During metaphase, chromosomes align at the cell's equatorial plane, also known as the metaphase plate. This alignment is crucial for the equal distribution of chromosomes to the daughter cells.
Differentiate between the stages: In prophase, chromosomes condense and become visible. In anaphase, sister chromatids separate and move to opposite poles. In telophase, the nuclear envelope re-forms around separated chromosomes.
Focus on the metaphase event: The alignment of chromosomes at the equatorial plane ensures that each daughter cell will receive an identical set of chromosomes during cell division.
Review the options given: The correct event for metaphase is the alignment of chromosomes at the cell's equatorial plane, distinguishing it from events in other stages of mitosis.
