title: Message sequences and short repetitive sequences are interspersed in sea urchin egg poly(A)+ RNAs.
abstract: At least half of the mass and most of the different single-copy maternal mRNA sequences in the egg are covalently associated with transcripts of short repetitive sequences. Only a restricted group of the diverse genomic repeat families are significantly represented. The messages fall into several hundred sets, each containing transcripts from a different repeat family.
