WebbA ribozyme is an RNA molecule with a well-defined tertiary structure that enables it to act like a protein enzyme in catalyzing biochemical and metabolic reactions within a cell. … 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. The 1982 discovery of ribozymes demonstrated that RNA can be both genetic material (like DNA) and a biological catalyst (like protein enzymes), and contributed to the RNA world hyp…
