What does rRNA stand for?

• A. Ribosomal RNA
• B. Relational RNA
• C. Regulatory RNA
• D. Recombinant RNA

Answer: (A)

Ribosomal RNA is the RNA component of ribosomes, the molecular machines that synthesize proteins by translating mRNA. The “r” in rRNA stands for ribosomal, and this RNA combines with proteins to form the ribosome’s core, where it helps position tRNAs and catalyze peptide bond formation during translation. Other phrases aren’t standard categories for this purpose: Relational RNA isn’t a recognized type; Regulatory RNA refers to RNAs that control gene expression elsewhere in the cell; Recombinant RNA describes RNA engineered in the lab. So the correct expansion is Ribosomal RNA.
