title: Sequences around the 3'-end of a ribosomal RNA gene of hamster mitochondria. Further support for the 'transcriptional attenuation' model.
abstract: We have determined DNA sequences near and beyond the end of the large ribosomal subunit RNA gene of hamster mitochondria. They indicate that (1) at least 20% of the rRNA transcripts terminate beyond the gene, in the downstream tRNAleu gene; (2) a transcription-attenuator-like structure occurs just upstream from the end of the rRNA gene; and (3) a conserved reading frame (' URF1 ') has an unusual initiation codon, GTG, in rodent mitochondria.
