question 49
during which phase of mitosis do the chromosomes line up at the equator of the cell?
1.prophase
2.metaphase
3.anaphase
4.telophase

Explanation:

• Prophase: Chromosomes condense, nuclear envelope breaks down.
• Metaphase: Chromosomes line up at the equator (metaphase plate) of the cell.
• Anaphase: Sister chromatids separate and move to opposite poles.
• Telophase: Nuclear envelopes reform around the separated chromosomes.

Since the question asks when chromosomes line up at the equator, the key event described matches metaphase.

Answer:

1. metaphase
