Which one is not true about nucleolus
- Cell Biology of the Nucleolus:
- The nucleolus is a dense, non-membrane-bound subnuclear organelle organized around Nucleolar Organizer Regions (NORs).
- Its established biological functions include:
- Synthesis and processing of precursor ribosomal RNA (pre-rRNA).
- Assembly of pre-ribosomal subunits with ribosomal proteins imported from the cytoplasm.
- Cells typically contain 1 to 3 (or 4) nucleoli depending on metabolic protein synthesis rates.
- Behavior During Cell Division:
- The nucleolus does NOT take part in cell division.
- During mitotic prophase, the nucleolus completely disassembles and vanishes, reforming in telophase around NORs.
- nalysis:
- (Takes part in cell division): Correct (this statement is false/not true).
