Question
What is the most critical role of ribosomal RNA (rRNA) in cellular biology?
Correct Answer

Detailed Explanation
rRNA is the main structural component of ribosomes. It also has catalytic functions; in the large ribosomal subunit, rRNA (not protein) catalyzes the formation of peptide bonds during translation (it is a ribozyme).
