ŠORM Y1 - 1966/11/01 UR - http://molpharm.aspetjournals.org/content/2/6/608.abstract N2 - The binding of valyl-tRNA to ribosomes in vitro, stimulated by guanylyl-uridylyluridine and guanylyl-uridylyl-cytidine is not effected by guanylyl-uridylyl-6-azacytidine. This finding indicates the high chemical specificity of the pyrimidine components of the codon. We express our thanks to the workers of the Isotope Laboratory of this Institute for radioactivity counts. ER -
