title: [RNA synthesis in embryogenesis of Drosophila virilis].
abstract: The synthesis of different RNA fractions labelled by 3H-uridine has been studied at different developmental stages in Drosophila virilis by means of thermal phenol extraction and chromatography on oligo-alphaT-cellulose. There are two periods of intensive synthesis of poly-A containing (messenger) RNA in the course of embryogenesis. The former (6--12 hrs) is the period of gastrulation and stomodeum development and the latter (15--21 hrs) is the period of intensive differentiation of larval organs. The synthesis of poly-A free RNAs predominates at the stages of blastoderm (2--5 hrs) and mesoderm segmentation and embryo shortening (12--15 hrs).
