A ribozyme is composed of which type of molecule and functions as what?

Explanation:
Riboenzymes are RNA molecules that act as enzymes, meaning they catalyze chemical reactions. This is possible because RNA can fold into complex shapes with functional groups positioned to act as catalysts or to coordinate metal ions, allowing reactions to proceed without proteins. That’s why the correct idea is that a ribozyme is made of RNA and functions as an enzyme. DNA stores genetic information, proteins are the typical enzymes, and lipids are structural components or fuels, not catalytic RNA. Ribozymes show that RNA can both carry genetic information and catalyze reactions, with examples like hammerhead ribozyme and RNase P.
