Verified step by step guidance

Understand the function of ribosomes: Ribosomes are cellular structures responsible for protein synthesis. They translate messenger RNA (mRNA) into polypeptide chains.

Identify the main components of ribosomes: Ribosomes are composed of ribosomal RNA (rRNA) and proteins. These components form two subunits, a large and a small subunit, which come together during protein synthesis.

Differentiate between ribosomal components and other cellular structures: Mitochondrial DNA, lysosomal enzymes, and the Golgi apparatus are not part of ribosomes. Mitochondrial DNA is found in mitochondria, lysosomal enzymes are involved in digestion within lysosomes, and the Golgi apparatus is involved in modifying, sorting, and packaging proteins.

Focus on ribosomal RNA (rRNA): rRNA is a crucial component of ribosomes, providing structural and functional roles in the ribosome's ability to synthesize proteins.

Conclude with the correct identification: Based on the understanding of ribosome structure, ribosomal RNA (rRNA) is the correct component associated with ribosomes.
