Telophase is characterized by what event?

Telophase is characterized by what event?

• A. Chromosomes begin to uncoil and spindles break down, and a new nuclear membrane forms.
• B. Spindle apparatus forms to separate chromatids.
• C. DNA replication occurs.
• D. Cytokinesis begins.

Answer: (C)

Telophase brings mitosis to its end by reversing the tight condensation of chromosomes from earlier stages. Here, the chromosomes uncoil back into less visible chromatin, and two new nuclear membranes re-form around each chromosome set, signaling the return to distinct nuclei. The spindle apparatus breaks down as these processes complete. DNA replication happens during S phase, not during mitosis; the spindle forms earlier in prophase to separate chromatids. Cytokinesis often begins during telophase or overlaps with it, but the defining event of telophase is the re-formation of the nuclear envelopes and the de-condensation of chromosomes. So the description that fits telophase best is chromosomes uncoiling, spindles breaking down, and a new nuclear membrane forming.
