Which RNA molecule still catalyzes reactions?

Explanation:
RNA can act as an enzyme, not just as a messenger or adaptor. Some RNA molecules fold into shapes that create an active site and speed up chemical reactions—these catalytic RNAs are called ribozymes. They demonstrate that RNA itself can catalyze biochemical steps, which is why they’re described as non-protein enzymes. The ribosome’s RNA component participates in the catalytic step of peptide bond formation, showing that RNA can do catalysis within a complex. However, when we're focusing on a distinct category of RNA with enzymatic activity outside of a protein catalyst, ribozymes are the best answer. The other RNAs primarily serve informational or structural roles in translation, rather than acting as catalysts on their own.
