The function of the nucleolus is to form:
Correct answer: C. rRNA
- A. Nuclear envelope
- B. Chromosome
- C. rRNA
- D. Cytoplasm
Explanation
The nucleolus is a region within the nucleus of eukaryotic cells where ribosome synthesis occurs. Its primary function is to transcribe and assemble the ribosomal RNA (rRNA) molecules, which are essential components of ribosomes. Ribosomes are responsible for protein synthesis in cells.The nucleolus performs the following functions:1. rRNA transcription: Transcribes the rRNA genes into rRNA molecules.2. rRNA processing: Processes the transcribed rRNA molecules into mature rRNA.3. Ribosome assembly: Assembles the rRNA molecules with proteins to form complete ribosomes.
