Abstract
1. Nucleic acids of whole Drosophila adults were prepared in good yield and substantially free from impurities by new modifications of the phenol method. 2. The average molar base compositions of the DNA (41% of guanine+cytosine) and transfer RNA (60% of guanine+cytosine) resemble those of mammalian nucleic acids; the ribosomal RNA has a DNA-like molar base composition (43% of guanine+cytosine), and it is considered that this is reflected in the lower stability of its secondary structure compared with mammalian ribosomal RNA. 3. The two main ribosomal forms were separated and average base compositions and sedimentation values determined.
