Where is ribosomal RNA synthesized within the cell?

Nucleus

Ribosome

Nucleolus

Ribosomal RNA (rRNA) is synthesized in the nucleolus, a specialized structure within the nucleus of eukaryotic cells. The nucleolus is responsible for the transcription of rRNA genes, and it plays a crucial role in the assembly of ribosomes, which are made up of rRNA and proteins. The nucleolus not only contains the necessary DNA for rRNA production but also contains enzymes and proteins that facilitate the transcription and processing of rRNA. This process is vital for ribosome assembly, as ribosomes are essential for protein synthesis in all living cells. Understanding the function of the nucleolus highlights its importance in gene expression and cellular function.
