Question

Which of the cellular structure always disappears during mitosis?

• A. Cell wall
• B. Cell membrane
• C. Nucleolus
• D. All of the above

Answer 1

The correct option is C Nucleolus

The nucleolus always disappears at the onset of mitosis during prophase. In prophase, chromatin in the nucleus begins to condense and becomes visible in the light microscope as chromosomes. The nucleolus disappears. Centrioles begin moving to opposite ends of the cell.

So, the correct answer is option C.
