Understand the stages of mitosis: Mitosis is divided into several phases: prophase, metaphase, anaphase, and telophase.
Identify the characteristics of each phase: In prophase, chromosomes condense and become visible under a microscope. In metaphase, chromosomes align at the cell's equatorial plate. In anaphase, sister chromatids separate and move to opposite poles. In telophase, chromosomes de-condense and nuclear membranes reform.
Focus on prophase: During prophase, chromatin fibers condense into discrete chromosomes, making them visible. This is the first stage of mitosis where such condensation occurs.
Recognize the significance of chromosome condensation: Condensation is crucial for the chromosomes to be efficiently segregated into daughter cells during cell division.
Conclude that the phase where chromosomes condense is prophase, as this is when they first become visible and start the process of mitosis.
