During which phase of mitosis does the mitotic spindle form?

• A. Telophase
• B. Prophase
• C. Metaphase
• D. Anaphase

Answer: (B)

Verified step by step guidance

1. Understand the stages of mitosis: Mitosis is divided into several phases: prophase, metaphase, anaphase, and telophase.
2. Identify the key events in each phase: During prophase, the chromatin condenses into visible chromosomes, and the mitotic spindle begins to form.
3. Recognize the role of the mitotic spindle: The mitotic spindle is crucial for separating chromosomes during cell division.
4. Recall that the mitotic spindle formation is initiated in prophase: This is when the spindle fibers start to emerge from the centrosomes.
5. Conclude that the mitotic spindle forms during prophase, as this is the phase where the spindle apparatus is assembled and becomes visible.
