Vedclass · Answer

(D) Most enzymes are proteinaceous in nature. However,there are certain $RNA$ molecules that possess catalytic activity and are known as ribozymes. Ribonuclease-$P$ is a well-known example of a ribozyme,which is an $RNA$ enzyme that cleaves $RNA$ molecules. Therefore,ribozyme and ribonuclease-$P$ are exceptions to the rule that all enzymes are proteins.
