abstract：:It has been suggested that inorganic membranes were forerunners of organic membranes at the origin of life. Such membranes, interposed between alkaline fluid in submarine vents and the more acidic Hadean ocean, were thought to house inorganic molecular machines. H+ flowed down the pH gradient (ΔpH) from ocean to vent ...

In such a chain elongation reaction, the Tetrahymena ribozyme was found to select 3',5'-linked substrates from a pool that contained a large molar excess of 2',5...
