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, which combines with proteins to form ribosomal subunits.

Differentiate between the nucleolus and other nuclear components: The nuclear envelope surrounds the nucleus and contains nuclear pores that regulate the passage of molecules. However, these structures are not involved in ribosome assembly.

Clarify the role of mitochondria: Mitochondria are organelles responsible for energy production in the cell, not for ribosome assembly or rRNA synthesis.

Conclude that the nucleolus is the correct answer: Based on its specific function in ribosome and rRNA assembly, the nucleolus is the part of the nucleus responsible for these processes.
