title: Oligomeric sequences in the cytoplasmic RNA of sea urchin embryos.
abstract: Oligomeric stretches of adenylate and uridylate and polymeric segments of adenylate have been shown to exist in sea urchin embryo hnRNA. It is demonstrated here that at least some oligo(U)-enriched sequences are conserved in sea urchin cytoplasmic RNA, whereas apparently few, if any, oligo(A) sequences are so conserved.
