During the past few decades we have witnessed an era of remarkable growth in the field of molecular biology. In 1950 very little was known ofthe chemical constitution of biological systems, the manner in which information was transmitted from one organism to another, or the extent to which the chemical basis of life is unified.  Meer

The slowly acting amatoxins bind to the DNA dependent nucleoplas­ mic RNA polymerase B (II) which is responsible for the transscription of m-RNA. This enables one to discriminate between form Band polymerase A (I), the enzyme catalyzing r-RNA synthesis, and to recognize all bio­ logical events depending on m-RNA synthesis (protein synthesis after hormonal stimulation, growth of certain virus species etc.  Meer
