Verified step by step guidance1
Understand the function of the nucleolus: The nucleolus is a region found within the nucleus of eukaryotic cells. Its primary function is to produce and assemble ribosome components.
Identify the components associated with ribosome production: The nucleolus is responsible for synthesizing ribosomal RNA (rRNA) and combining it with proteins to form the subunits of ribosomes.
Differentiate between the options provided: Mitochondrial DNA is found in mitochondria, lysosomal enzymes are found in lysosomes, and chlorophyll is found in chloroplasts of plant cells.
Recognize that ribosomal RNA (rRNA) is the correct component associated with the nucleolus, as it is directly involved in ribosome assembly.
Conclude that the nucleolus contains ribosomal RNA (rRNA), which is essential for the formation of ribosomes, the cellular machinery for protein synthesis.
