In which mitotic phase do the chromosomes condense and the mitotic spindle begin to 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 characteristics of prophase: 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 the chromosomes during cell division.
4. Differentiate between the phases: In metaphase, chromosomes align at the cell's equatorial plane; in anaphase, sister chromatids separate; in telophase, the cell prepares to divide.
5. Conclude that the phase where chromosomes condense and the mitotic spindle begins to form is prophase.
