Question

which phase of mitosis is characterized by the following events:1. chromosomes condense and become visible.2. spindle fibers begin to form.3. the nuclear envelope begins to break down.a. anaphaseb. telophasec. prophased. metaphase

Explanation:

To determine the mitosis phase, we analyze each option:

• Anaphase (A): Chromatids separate and move to poles, not matching the events.
• Telophase (B): Involves nuclear envelope reformation and cell division, not the listed events.
• Prophase (C): Chromosomes condense, spindle fibers form, and nuclear envelope breaks down—matching all three events.
• Metaphase (D): Chromosomes align at the equator, not the described events.

Answer:

C. Prophase
