A new silver staining technique was used for studying the action of Rifamycin on the transcriptional activities of nucleolar genes. Nucleoli of untreated cells were abundantly packed with silver grains upon staining. Rifamycin inhibits the transcription of nucleolar rDNA, resulting in a central clear area devoid of silver grains which on recovery reverts to(More)
