Verified step by step guidance
1
Understand the stages of mitosis: Mitosis is divided into several phases: prophase, metaphase, anaphase, and telophase.
Identify the key events in each phase: In prophase, the chromatin condenses into visible chromosomes, and the nuclear envelope begins to disintegrate.
Focus on the formation of the spindle apparatus: The spindle apparatus is crucial for separating chromosomes during mitosis.
Recognize when the spindle apparatus begins to form: During prophase, the centrosomes move to opposite poles of the cell, and the spindle fibers start to emerge from them.
Conclude that the spindle apparatus begins to form during prophase, as this is when the necessary structures start to develop and organize for chromosome separation.
