| Abstract: | The subcellular distribution of chick embryo low molecular weight RNAs has been studied by the thermal phenol fractionation procedure. The major part of 8SII RNA, earlier discovered in some oncornaviruses and normal cells, was extracted by phenol at 4%. Our results thus give evidence of the cytoplasmic localization of this RNA. Another part of 8SII RNA, which has been extracted at 65 degrees, is thought to consist of newly synthesized molecules located in the nuclei. A similarity in subcellular distribution of low molecular weight RNAs from chick embryo and rat liver has been obtained, i. e. such a distribution may be of universal nature. |
