Phosphocellulose chromatography has been employed to characterize RNA polymerase I present in two different functional states in rat liver cells. The actively transcribing enzyme solubilized from nuclei appears to belong both to the IA and IB classes, whereas the non-transcribing enzyme present in the cytoplasmic fraction has been found to belong only to… CONTINUE READING
