Question

what happens during prophase? the sister chromatids separate and move to the opposite sides of the cell. the chromosomes condense, and the nuclear membrane disappears. the cell grows, replicates its dna, and gets ready to divide. the cytoplasm divides, and the two daughter cells separate.

Explanation:

To determine what happens during prophase, we analyze each option:

• "The sister chromatids separate and move to the opposite sides of the cell" describes anaphase.
• "The chromosomes condense, and the nuclear membrane disappears" is the correct description of prophase (chromosomes condense from chromatin, and the nuclear envelope breaks down).
• "The cell grows, replicates its DNA, and gets ready to divide" describes interphase.
• "The cytoplasm divides, and the two daughter cells separate" describes cytokinesis.

Answer:

The chromosomes condense, and the nuclear membrane disappears.
