Identification of a short form of a Caenorhabditis elegans Y RNA homolog Cel7 RNA.

Cel7 RNA is a member of the Caenorhabditis elegans stem-bulge RNAs (sbRNAs) that are classified into the Y RNA family based on their structural similarity. We identified a 15-nucleotide-shorter form of Cel7 RNA and designated it Cel7s RNA. Both Cel7 and Cel7s RNAs increased during the development of worms from L1 to adult.
