title: The nucleotide sequence of 5S ribosomal RNA from the parasitic nematode Ascaris suum. Evolutionary relationships in nematodes.
abstract: We have determined the nucleotide sequence of 5S ribosomal RNA from the parasitic nematode Ascaris suum. The analysis of all Nematoda 5S rRNAs and their genes shows that this group must have diverged from other Metazoa at early stages of evolution. This conclusion is supported by the sequence variability in single-stranded regions which are strongly conserved in animal 5S rRNAs.
