[Chromosome nucleolus organizer regions of the African green monkey].
The silver staining Ag-I for detection of nucleolar organizer regions (NOR) in the African green monkey chromosomes was used. NOR were situated on the secondary constrictions of one pair of homologous marker chromosomes and consisted of two parts. A block of condensed chromatin was seen in the middle of the despiralized portion corresponding to the secondary constriction. The data suggest that the stalks of satellites of chromosomes, rather than satellites themselves, are regions of nucleolar organizer.
