rRNA (ribosomal RNA) has catalytic activity, helping form peptide bonds during protein synthesis.
Ref: NCERT Class 12 Biology Chapter 5: Molecular Basis of Inheritance Search for Genetic Material and RNA World
Ribozymes are RNA molecules that have enzymatic activity.
Ref: NCERT Class 11 Biology Chapter 9: Biomolecules Chemical Analysis and Biomolecules - Amino Acids Lipids
Traditional view that all enzymes are proteins was challenged by discovery of self-splicing rRNA in Tetrahymena by Cech and RNase P RNA by Altman. These RNAs catalyze phosphodiester bond cleavage and formation, proving catalytic RNA. In RNA world, ribozymes could replicate, process tRNA and synthesize peptides. Modern biology retains ribosomal peptidyl transferase as ribozyme. Understanding catalytic RNA bridges chemical and biological evolution. Hence definition Catalytic RNA molecules captures essential feature linking genotype and phenotype in early life. This concept integrates genetics, e
