WebThe montmorillonite-catalyzed reactions of the 5′-phosphorimidazolide of adenosine used as a model generated RNA type oligomers. These reactions were found to be dependent on the presence of mineral salts. Whereas montmorillonite (pH 7) produced only dimers and traces of trimer in water, addition of sodium chloride (0.1–2.0 M) enhanced the chain length of … WebNov 9, 2024 · RNA Interference (RNAi) Introduction.
