Transcriptional organization of the 5.8S ribosomal RNA ristron in Xenopus laevis ribosomal DNA
Division of Molecular and Cellular Biology, National Jewish Hospital and Research Center and Department of Biophysics and Genetics, University of Colorado School of Medicine Denver, CO, USA
Received December 13, 1976. Hybridization of purified,32P-labeled 5.8S ribosomal RNA from Xenopus laevis to fragments generated from X. laevis rDNA by the restriction endonu-clease, EcoRI, demonstrates that the 5.8S rRNA cistron lies within the transcribed region that links the 18S and 28S rRNA cistrons.
