| Abstract: | In Nereidae the experimental suppression of the brain hormone activity (brain removal) sets up a diminution of stable RNA (18-28 S rRNA, 4-5 S RNA) syntheses, during oogenesis. Quantitative analysis of RNA, carried out on oocytes maintained during 12 days after brain removal, shows a diminution in RNA with regard to the controls. Sedimentation profiles of RNA synthetized after brain removal suggest that an alteration occurs in the processing of 45 S rRNA. In Nereidae, the brain hormone controls the storage of stable oocyte RNA through an action, not at the transcription level, but on the processing of this RNA. |
