amanitin inhibits the incorporation of uridine into the nucleoplasmatic rna , whereas incorporation into the rna of nucleoli is hardly or not at all influenced.we conclude that , in agreement with findings on animal cells , alpha-amanitin inhibits at least one of the rna-polymerases localized in the nucleoplasm but does not markedly influence the rna-polymerase of the nucleoli .
