WebQuizlet 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) … Ver mais Before the discovery of ribozymes, enzymes—which are defined as catalytic proteins —were the only known biological catalysts. In 1967, Carl Woese, Francis Crick, and Leslie Orgel were the first to suggest that RNA … Ver mais Although ribozymes are quite rare in most cells, their roles are sometimes essential to life.
