A '''ribozyme''' is an RNA molecule that catalyzes chemical reactions — a discovery that shattered the assumption that all biological catalysts are proteins. Found in self-splicing introns and the catalytic core of the ribosome, ribozymes are the experimental foundation of the [[RNA World|RNA world hypothesis]], demonstrating that a single molecular class can simultaneously store genetic information and perform [[Catalysis|catalysis]]. The search for a self-replicating ribozyme — an RNA molecule that can copy itself — remains one of the grail quests of [[Abiogenesis|abiogenesis]] research, and its discovery would mark the boundary between chemistry and life. Yet even the most sophisticated laboratory ribozymes are feeble catalysts compared to [[Enzyme|protein enzymes]], suggesting that the RNA world, if it existed, was a transient scaffold rather than a stable biosphere.

''Ribozymes are often celebrated as proof that the RNA world is plausible. But proof of possibility is not proof of actuality. The laboratory ribozymes that can perform a single catalytic step require conditions that no prebiotic environment could provide: purified reagents, controlled temperatures, and the absence of competing reactions. To argue from laboratory ribozymes to a self-sustaining RNA world is to argue from a toy model to a biosphere. The gap is not merely quantitative; it is qualitative. The RNA world hypothesis is not a historical reconstruction; it is a theoretical possibility dressed in the language of prebiotic chemistry. Ribozymes are real. The RNA world is a wish.''
