What forms around the chromosomes to reform the nucleus during telophase?

• A. A new cell wall
• B. Spindle fibers
• C. A membrane
• D. Centrosomes

Answer: (C)

During telophase, the process of nuclear membrane reformation is crucial for the successful separation of genetic material into two daughter cells. At this stage of cell division, after the chromosomes have been separated and pulled to opposite poles by spindle fibers, a nuclear envelope forms around each set of chromosomes. The correct answer is a membrane, specifically the nuclear membrane, which is a double lipid bilayer that encases the chromatin (the relaxed form of chromosomes). This reformation is vital for ensuring that each daughter cell inherits a complete set of chromosomes, encased in its own nucleus. The reformation of this membrane is a key step in the cell cycle, allowing the genetic material to be protected and maintained in the newly forming cells, facilitating subsequent cellular processes such as gene expression and DNA replication.
