During which stage of mitosis does the nuclear envelope begin to reform around the separated chromosomes?
Solution
Correct Answer: Option C
- During mitosis, the cell undergoes a series of stages to ensure accurate division of genetic material into two daughter cells.
- The nuclear envelope begins to reform around the separated chromosomes during telophase.
Here is a brief overview of the relevant stages:
- In prophase, the chromatin condenses into visible chromosomes, and the nuclear envelope starts to break down.
- During metaphase, chromosomes align at the metaphase plate in the center of the cell.
- In anaphase, sister chromatids are pulled apart toward opposite poles of the cell.
- Finally, in telophase, the chromosomes arrive at the poles, and the nuclear envelope reassembles around each set of chromosomes, effectively creating two distinct nuclei. This marks the near end of mitosis before cytokinesis completes cell division.
Thus, the correct answer is telophase, as it is the stage when the nuclear envelope reforms.
