RESUMO
The nucleotide sequences of 5S rRNAs from the starfish Asterias vulgaris, the squid Illex illecebrosus, the sipunculid Phascolopsis gouldii and the jellyfish Aurelia aurita were determined. The sequence from Asterias lends support for one of two previous base pairing models for helix E in metazoan sequences. The Aurelia sequence differs by five nucleotides from that previously reported and does not violate the consensus secondary structure model for eukaryotic 5S rRNA.
