Question

what happens during prophase?
the chromosomes condense, and the centrioles move toward opposite sides of the cell.
the sister chromatids are pulled apart to the opposite sides of the cell.
two daughter cells form as the cytoplasm divides.
the chromosomes align in the center of the cell.

Explanation:

Prophase is the first stage of mitosis. During this stage, chromatin condenses into visible chromosomes, and in animal cells, centrioles migrate to opposite poles of the cell to form the spindle apparatus. Sister chromatids being pulled apart occurs in anaphase, cytoplasm dividing to form daughter cells is cytokinesis, and chromosomes aligning at the cell center happens in metaphase.

Answer:

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