Which event is described for Telophase in the material?

• A. Chromosome condensation
• B. Nuclear envelope appears
• C. Cytokinesis occurs
• D. DNA replication

Answer: (B)

Telophase centers on reassembling the nucleus after the chromosomes have arrived at the poles and begun to de-condense. The defining event is the re-formation of the nuclear envelope around each set of chromosomes, creating two separate nuclei within the cell. This contrasts with chromosome condensation, which happens earlier in prophase, and with DNA replication, which occurs during interphase (S phase). Cytokinesis, the division of the cytoplasm, typically overlaps with late telophase but is not the signature event of telophase itself.
