Abstract/OtherAbstract:
|
Miller's technique was applied to isolated nuclei of rat liver. Both the usual nucleolar and non-nucleolar transcription complexes were visualized. In addition, an unusual type of putative non-ribosomal transcription unit was revealed. It was charcaterized by a high density of the lateral ribonucleoprotein (RNP) fibrils. Although these particular units exhibited a regular increase of fibril lengths, the length of the transcript-covered deoxyribonucleoprotein (DNP) fibres and the morphological aspect of the RNP fibrils distinguished them from the nucleolar 'Christmas-tree'-like figures. The linear and granular configuration of the transcripts and the absence of terminal knobs made them similar to non-nucleolar nascent RNP fibrils. |
