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.

Note added in proof: The characteristics of sea urchin egg p(A)^+ RNA described here pertain as well to the p(A)^+ RNA of Xenopus, an anuran vertebrate. When p(A)^+ RNA from the unfertilized egg of Xenopus (obtained by Dr L. Dennis Smith) was renatured and spread for electron microscopy under the exact conditions of Fig. 2 (by M. E. Chamberlin), the following results were obtained. (1) RNA which was not permitted to anneal after denaturation displayed only occasional intrastrand foldback structures. (2) RNA renatured to C_0t 60 was largely involved in structures containing two to four molecules bound by short ,duplex regions. And (3), RNA renatured to C_0t 600 was largely included in complex multimolecular aggregates often containing more than 10 molecules.
