p.7 mitosis and the cell cycle
collect 6 tokens
what happens during metaphase?
the cell grows, replicates its dna, and gets ready to divide.
the chromosomes condense, and the nuclear membrane disappears.
a nuclear membrane forms around each set of dna.
the chromosomes line up in the middle of the cell.

Explanation:

To solve this, we analyze each option based on mitosis stages:

• Option 1: Describes interphase (growth, DNA replication), not metaphase.
• Option 2: Describes prophase (chromosome condensation, nuclear membrane breakdown), not metaphase.
• Option 3: Describes telophase (nuclear membrane formation), not metaphase.
• Option 4: In metaphase, chromosomes align at the cell's equatorial plate (middle).

Answer:

The chromosomes line up in the middle of the cell.
