A Cytochemical Study of Ribonucleic Acid Distribution in the Spermatogenic Cells of Drosophila virilis
Abstract
The distribution of RNA in the spermatogenic cells of D. virilis was studied by staining with azure B. All the spermatogenic cells with the exception of the sper matozoa were found to be rich in RNA. Most of this RNA was probably associated with ribosomes in the cytoplasm. The nucleolus of the meiotic prophase stages contained RNA and showed changes in its staining intensity, size shape, and location within the nucleus during the growth stage of the primary spermatocytes. These changes were probably associated with the various metabolic activities occurring in the spermatogenic cells. The nucleoli of the spermatids were much smaller than that of the meiotic prophase stages and stained less intensely. © 1977, Japan Mendel Society, International Society of Cytology.
