Variability in the molecular organization of the 5S RNA genes among strains of Drosophila melanogaster.
نویسنده
چکیده
The organization of the 5S RNA cluster has been analyzed in four strains of Drosophila melanogaster by the Southern technique. In some of the strains the 5S RNA cluster appears to be interrupted by an unrelated sequence. In other strains a continuous cluster is present.

Genetic analysis of the 5S RNA genes in Drosophila melanogaster.
The 5S RNA genes of Drosophila melanogaster in either an isogenic wildtype or a multiply inverted (SM1) chromosome 2 increase their multiplicity when opposite a deficiency for the 5S gene site. This is analogous to the compensation phenomenon previously described for the 18S and 28S ribosomal RNA genes of the X chromosome nucleolus organizer region. Molecular hybridization of 5S RNA to DNA cont...

Background: In this study, the toxicity of the different xenobiotics was tested on the fruit fly Drosophila melanogaster model system. Methods: Fly larvae were raised on food supplemented with xenobioticsat different concentrations (sodium nitroprusside (0.1-1.5 mM), S-nitrosoglutathione (0.5-4 mM), and potassium ferrocyanide (1 mM)). Emergence of flies, food intake by larvae, and pupation h...
متن کاملThe synthesis of 5S RNA and its relationship to 18S and 28S ribosomal RNA in the bobbed mutants of Drosophila melanogaster.
Ribosomes contain one molecule each of 5S, 18S and 28S RNA. In Drosophila melanogaster although the genes for 18S + 28S are physically separated from the 5S RNA genes, the multiplicity of various ribosomal RNA genes is roughly the same. Thus a coordinate synthesis of these three molecules might seem feasible. This problem has been approached by determining the molar ratios of various RNA's in o...
متن کاملConcentration dependent effect of morphine, aspirin, capsaicin and chili pepper hydro alcoholic extract on thermal and chemical pain model in fruit fly (Drosophila melanogaster)
Introduction: Pain research using animal models is related to ethical concerns, so invertebrates and insects have been recommended by researchers. In the present study, the nociceptive and antinociceptive effects of capsaicin, aspirin, morphine and chili extract were examined using fruit fly (Drosophila melanogaster) as an alternative for rodent pain model. Methods: Stage 3 of larvae and ad...
