Question

what happens during prophase? the chromosomes unravel. the chromosomes condense, and the centrioles move toward opposite sides of the cell. the chromosomes align in the center of the cell. the cell grows, replicates its dna, and prepares to divide.

Explanation:

During prophase of mitosis, chromosomes condense (become more tightly coiled and visible under a microscope). Centrioles (in animal cells) move to opposite poles of the cell. The other options: chromosomes unraveling is more related to telophase; chromosomes aligning in the center is metaphase; cell growing, replicating DNA is interphase (not prophase).

Answer:

The chromosomes condense, and the centrioles move toward opposite sides of the cell.
