Ribozymes (ribonucleic acid enzymes) are RNA molecules that have the ability to catalyze specific biochemical reactions, including RNA splicing in gene expression, similar to the action of protein enzymes.

Is an enzyme a protein or nucleic acid?

Enzymes are biological catalysts composed of amino acids; that is, they are proteins.

Are enzymes made of nucleic acids?

The term 'nucleic acid enzyme' is used to identify nucleic acids that have catalytic activity. Ribozymes (literally enzymes made of ribonucleic acid or RNA) are found in nature and mediate phosphodiester bond cleavage and formation and peptide bond formation.
