Stimulation by Rat Liver Ribonucleic Acid of Incorporation of Amino-acid into Rat Liver Ribosomes

Abstract

THE discovery1 that ribonucleic acid (RNA) and synthetic polyribonucleotides stimulated the incorporation of amino -acids into protein-like material in cell-free system from E. coli has been followed by many reports2–6 of similar findings with systems from the same and other cells. Rat liver RNA was shown5 to stimulate amino-acid incorporation when added to an E. coli system and rat liver RNA and polyuridylic acid caused increased incorporation of phenylalanine in a rat-liver microsomal system6. We wish to report that polyuridylic acid and rat liver RNA stimulate incorporation of amino-acid with rat liver ribo-somes.
