| first complete large subunit ribosomal rna sequence and secondary structure for a parasitic nematode: phylogenetic and diagnostic implications. | the complete sequence and secondary structure of the large subunit of nuclear ribosomal rna(lsurrna) were determined for the parasitic nematode labiostrongylus bipapillosus (order strongylida). its lsu rrna sequence was shorter (by 18 bp) than that of the free-living nematode, caenorhabditis elegans (order rhabditida), the only other species within the nematoda for which a complete lsu rrna sequence has been determined. interspecific differences in sequence were greater in the 12 d domains compa ... | 2003 | 12628592 |
