Utilizing a method which quantitatively extracts high molecular weight RNA, including intact precursor as well as mature ribosomal RNAs, adenylated molecules have been isolated from nuclear- and cytoplasmic-enriched fractions of Physarum microplasmodia labeled with [3H]-uridine. Electrophoretic analysis of denatured adenylated RNA from the nuclear-enriched fraction indicated the presence of a population of large molecules not found in the cytoplasmic-enriched fraction.
