Transcript text: During which phase does the nuclear membrane reform around the chromosomes?
Multiple Choice
Early metaphase
Prophase
Anaphase
Metaphase
Telophase
Solution
The answer is the last one (Telophase): the nuclear membrane reforms around the chromosomes.
Explanation for each option:
Early metaphase: Incorrect. During early metaphase, the nuclear membrane has already broken down, and the chromosomes are aligning at the metaphase plate.
Prophase: Incorrect. In prophase, the nuclear membrane begins to break down, and the chromosomes condense and become visible.
Anaphase: Incorrect. During anaphase, the sister chromatids are pulled apart to opposite poles of the cell.
Metaphase: Incorrect. In metaphase, the chromosomes are aligned at the metaphase plate, and the nuclear membrane is not present.
Telophase: Correct. During telophase, the nuclear membrane reforms around the separated chromosomes at each pole of the cell, leading to the formation of two distinct nuclei.
Summary:
The nuclear membrane reforms around the chromosomes during telophase.
