✦ Synopsis
A quantitative polyacrylamide gel electrophoresis procedure for the analysis of microgram quantities of RATA has been developed. The method was used to determine the rates of rRNA synthesis and the molar ratios of various RNA species in Drosophila females homozygous for either of two X chromosome inversions that result in sterility of the females and produce lethality in X/0 males. Evidence is presented that in these genotypes the rate of rRNA synthesis during oogenesis is unimpaired but the mature oocyte has a 10-12% reduction in rRNA content.
