Ag-NOR staining and a counterstain-enhanced fluorescence technique (chromomycin A3/distamycin A/DAPI staining = CDD-method) have been applied to ibex (Capra ibex L.), chamois (Rupicapra rupicapra L.) and bison (Bison bison L.) chromosomes. Chromomycin A3 visualization led to a well defined R-banding

The Ag-stainability of the nucleolus organizer region (NOR) was studied in the acrocentric chromosomes identified by Q-banding in cultured lymphocytes from seven children with trisomy 21 and their parents. The observed Ag-NOR patterns were in accordance with chromosomal inheritance except for a slig
Studies on chromatid aberration induction in NORs of standard and reconstructed karyotypes, as well as in the single translocation lines of barley, indicate a correlation between synthetic activity (transcription) of rDNA and frequency of chromosome mutations induced by HU. Experimental evidence in
The positions of the nucleolus organizer regions in metaphase chromosomes of Drosophila hydei were detected by in situ hybridization experiments. In agreement with earlier conclusions the nucleolus of the X chromosome was found to originate in a terminal region of the heterochromatic arm. The Y chro
The inheritance of nucleolus organizer regions (NORs) was investigated by examining the degree of silver-staining in individual acrocentric chromosomes in two successive generations. The study was undertaken in six Down's syndrome children and their respective parents. Quinacrine fluorescent polymor
