The nucleotide sequences of 5S rRNAs from a rotifer, Brachionus plicatilis, and two nematodes, Rhabditis tokai and Caenorhabdik elegans

Abstract

The nucleotide sequences of 5S rRNAs from a rotifer, Brachionus pticatitis, and two nematodes, Rhabditis tokai and Caenorhabditis etegans have been determined. The rotifer has two 5S rRNA species that are composed of 120 and 121 nucleotides, respectively. The sequences of these two 5S rRNAs are the same except that the latter has an additional base at its 3′-terminus. The 5S rRNAs from the two nematode species are both 119 nucleotides long. The sequence similarity percents are 79% (Brachionus/Rhabditis), 80% (Brachionus/Caaorhabditis), and 95% (Rhabditis/Caenorhabditis) among these three species. Brachionus revealed the highest similarity to Linguh (89%), but not to the nematodes (79%). © 1982 IRL Press Limited.
