Verified step by step guidance

Understand the function of the nucleolus: The nucleolus is a prominent sub-structure within the nucleus of eukaryotic cells. Its primary function is to assemble ribosomes, which are essential for protein synthesis.

Recognize the role of ribosomal RNA (rRNA): Ribosomal RNA is a key component of ribosomes. The nucleolus is responsible for transcribing and assembling rRNA with proteins to form ribosomal subunits.

Differentiate between the nucleolus and other nuclear components: The nuclear envelope surrounds the nucleus and contains nuclear pores for transport, but it does not assemble ribosomes. The mitochondria are involved in energy production, not ribosome assembly.

Identify the nucleolus as the correct answer: Given the options, the nucleolus is the only structure within the nucleus that is directly involved in the assembly of ribosomes and rRNA.

Conclude with the importance of the nucleolus: Emphasize that the nucleolus plays a crucial role in cellular function by facilitating the production of ribosomes, which are necessary for translating genetic information into proteins.
