Guida verificata passo dopo passo1
Understand the stages of mitosis: Mitosis is divided into several phases: prophase, metaphase, anaphase, and telophase.
Identify the key characteristics of each phase: In prophase, chromosomes condense and become visible. In metaphase, chromosomes align at the cell equator. In anaphase, sister chromatids separate. In telophase, the cell prepares to divide.
Focus on metaphase: During metaphase, the chromosomes are fully aligned at the metaphase plate, which is the cell equator.
Recognize the role of the spindle fibers: During metaphase, spindle fibers attach to the centromeres of the chromosomes, ensuring they are properly aligned for separation.
Conclude that the phase where chromosomes are fully aligned on the cell equator is metaphase, based on the characteristics of each mitotic phase.
