What is the function of the nucleolus?

Correct answer: C. Formation of ribosomes

  • A. Formation and breakdown of the nuclear envelope
  • B. Formation of the centromere
  • C. Formation of ribosomes
  • D. Organization of spindle fibers during nuclear division

Explanation

The nucleolus is a prominent sub-structure within the nucleus, noted for its lack of a membrane boundary. Its primary function is the production and assembly of ribosomal RNA (rRNA) and ribosome subunits, which are essential for protein synthesis in the cell. This is why it is often referred to as the 'ribosome factory' of the cell.Option C is correct because the nucleolus is directly involved in the formation of ribosomes.
