During telophase, what happens to the chromosomes?

• A. They condense further at the spindle equator
• B. They arrive at the poles and begin to de-condense
• C. They replicate
• D. They align at the center of the cell

Answer: (B)

During telophase, the chromosomes that have been pulled to opposite ends arrive there and begin to de-condense, returning from highly condensed forms to less visible chromatin. The nuclear envelope starts to re-form around each set of chromosomes, creating two separate nuclei, as the cell finishes the process of mitosis and moves toward completing division with cytokinesis. This stage follows the earlier events of condensation and separation and precedes the final split of the cytoplasm.
