摘要

The primary structure of the gene for 18 S rRNA of the crustacean Artemia salina was determined. The sequence has been aligned with 13 other smalll ribosomal subunit RNA sequences of eukaryotic, archaebacteriai, eubacterial , chloroplastic and plant mitochondrial origin. Secondary structure models for these RNAs were derived on the basis of previously proposed models and additional comparative evidence found 1n the alignment. Although there 1s a general similarity 1n the secondary structure models for eukaryotes and prokaryotes, the evidence seems to indicate a different topology 1n a central area of the structures.
