Abstract
The specific changes in the degradation of ribosomal RNA of Drosophila melanogaster were analyzed during the developmental stages. Severe degradation of rRNA was observed in the homogenates of the Specific stages (72, 144, and 168h old larvae) during the larval development from the results of polyacrylamide gel electrophoresis without purification of rRNA. It was suggested that this degradation of rRNA was induced by endogenous RNase contained in the larvae.
