Question

2 multiple choice 1 point during which phase does the spindle form, the nuclear membrane disappears, and the chromosomes take on a x - shape? telophase prophase anaphase metaphase

Explanation:

To solve this, we recall the stages of mitosis:

• Telophase: Involves nuclear envelope reformation and spindle breakdown (not matching the described events).
• Anaphase: Is about sister chromatids separating and moving to opposite poles (not matching).
• Metaphase: Chromosomes align at the equator (spindle is already formed, so not matching).
• Prophase: During prophase, the mitotic spindle forms, the nuclear membrane breaks down, and chromosomes condense into an X - shaped structure (due to sister chromatids being visible) as they prepare for metaphase.

Answer:

C. Prophase
