Question

what happens during prophase? chromosomes uncoil and spread out; chromosomes begin to tightly coil; chromatids are pulled away from each other; chromosomes line up in the center of the cell

Explanation:

Prophase is the first stage of mitosis. During this stage, chromatin (loose DNA) condenses into visible, tightly coiled chromosomes. Chromosomes uncoiling occurs in telophase, chromatids being pulled apart happens in anaphase, and chromosomes lining up at the cell center is metaphase.

Answer:

Chromosomes begin to tightly coil
