【 摘 要 】

The complete nucleotide sequence of the small ribosomal subunit RNA of the gastropod, Limicolaria kambeul, was determined and used to infer a secondary structure model. In order to clarify the phylogenetic position of the Mollusca among the Metazoa, an evolutionary tree was constructed by neighbor-joining, starting from an alignment of small ribosomal subunit RNA sequences. The Mollusca appear to be a monophyletic group, related to Arthropoda and Chordata in an unresolved trichotomy.
