The first steps of magnification of DNA complementary to ribosomal RNA in Drosophila malanogaster.
Those Drosophila bobbed males whose progeny exhibit the phenomenon of "rDNA magnification" are shown to have higher rates of rRNA synthesis than normal males. Further evidence that the magnification process is characterized by a stepwise accumulation of rDNA was obtained. A working hypothesis to explain the magnification process is advanced.
