Practice question · True or false
The nucleolus is a membrane-bound organelle within the nucleus.
Hints
- Is there a membrane separating the nucleolus from the rest of the nucleoplasm?
- It is a dense region of concentrated activity, not a bounded compartment.
Show the answer
False
Why
False, the nucleolus has no membrane. It is a dense region where ribosomal RNA is transcribed and ribosomal subunits assembled, held together by the concentration of activity itself rather than by a boundary.
