title: Chemical synthesis of oligoribonucleotides containing 2-aminopurine:  substrates for the investigation of ribozyme function.
abstract: The chemical synthesis of a fully protected ribonucleoside phosphoramidite, containing 2-aminopurine as the base component, and its incorporation into short oligoribonucleotides as substrates for an engineered ribozyme from Tetrahymena is described.
