Significant intra-individual variation in the sequences of the ribosomal RNA (rRNA) genes is highly unusual in animal genomes; however, two classes of both 18S and 28S rRNA gene sequences have been detected in chaetognaths, a small phylum of marine invertebrates. One species, Spadella cephaloptera Busch, 1851, is well-suited to the methods of in situ analysis of gene expression, since it is totally transparent. To test our hypothesis of a possible functional division of the two classes of genes… Expand
