Question

What types of changes do chromosomes undergo during the phases mitosis?

Answer 1

Explanation:

During this phase, the chromosomes inside the cell's nucleus condense and form tight structures. ... Important changes also take place outside of the nucleus during prophase. In particular, two structures called centrosomes move to opposite sides of the cell during this phase and begin building the mitotic spindle.

Answer 2

During mitosis, the two sister chromatids that make up each chromosome separate from each other and move to opposite poles of the cell.
