CIRCULAR DNA MOLECULES IN THE GENUS DROSOPHILA

[摘要] The satellite DNA's from the embryos of five species of Drosophila ( D. melanogaster, D. simulans, D. nasuta, D. virilis and D. hydei ) have been analyzed for the presence of closed circular duplex DNA molecules, as determined by CsCl-EBr gradients. Circular DNA molecules were found in every species but D. melanogaster . Analyses of cell fractions from adult Drosophila and organ fractions from Drosophila larvae show that fractions containing mitochondria are highly enriched in these molecules.
