Transcription of Complex Structural Genes in the , Oocyte System) and the addition of DNA to lysate of oocyte nuclei (Brown and Jordan 1978) or to a lysate fraction of entire cells (Weil et al. 1979). Finally, viruses carrying heterologous genes may be used to transform eukaryotic cells (Mulligan et al. 1979; Schaffner 1980) and yeast plasmids may carry genes into yeast (Beggs 1978; Hinnen et al. 1978).

The Association of Small Nuclear RNA Species with Rapidly Sedimenting Subnuclear Structurese synthesized by RNA polymerase C or III (Zieve et al. 1977), whereas nothing is known about the transcription of snRNA. The exact biological function of the small molecular weight RNA species remains widely obscure at present.

RNA Processing in Frog Oocytes Microinjected with Cloned Genesmber of different enzymatic reactions and would be very difficult to reproduce in vitro. We will review here our recent work on the processing of a spliced tRNA and will discuss some general features of RNA processing emerging from it.

Composition and Structural Organization of Nuclear Ribonucleoprotein in Amphibian Oocytesled RNA and labelled protein and has a density of 1.39 g cm. in CsCl. (iii) Most of the nucleoplasmic protein in the form of beaded aggregates which sediment at 10–20 S. These isolated structures are compared with the ultrastructural features of sectioned nuclei and their possible interrelationship is discussed.

Interaction of Eukaryotic Ribosomes with Messenger RNA: Evidence for a Scanning Mechanismlly increased binding of . ribosomes to the synthetase and A-protein cistrons, and also allowed initiation at a few spurious sites. Perturbation of mRNA structure also alters the specificity of initiation by eukaryotic ribosomes, but the effects are quite different from those observed in prokaryotic systems.

The Transcription of Satellite and Ribosomal DNA Sequences on Lampbrush Chromosomes of Crested Newtsnding with denatured labelled DNA. It will be obvious that the technique not only allows detection by autoradiography of the probe sequence in the axis of a lampbrush loop, but it also gives evidence of the transcription of that sequence.
