Abstract
The sequence complexity of the RNA present in mature oocytes of the sea urchin Arbacia punctulata was measured by DNA-RNA hybridization. Small quantities of single copy [^3H]DNA were hybridized with large excesses of RNA and the amount of [^3H]DNA-RNA hybrids formed was assayed by hydroxyapatite. At termination of the reaction, which follows pseudo-first-order kinetics, 2.6% of the reactable single copy [^3H]DNA mass is present in RNA-DNA hybrids. This DNA was isolated, shown to be rehybridizable to RNA and, within the range of detectability, to consist solely of nonrepetitive sequences. Assuming asymmetric transcription, 5.2% of the genomic single copy sequence, or 3.0 × 10^7 nucleotides, is represented in oocyte RNA. The kinetics of hybridization indicate that these sequences are included in approximately 1–2% of the oocyte RNA.
