摘要：
The Ag-staining of the nucleolus organizer regions (NORs) of prematurely condensed chromosomes (PCCs) of human cells showing different degrees of rRNA-gene activity clearly indicates a close correlation between the positive Ag-staining of NORs and the activity of rRNA genes. The Ag-stain, however, seems insensitive to low rates of rRNA synthesis and obviously follows a threshold reaction. Furthermore it was found that the frequency of Ag-positive chromosomes involved in satellite associations in interphase does not differ from that in metaphase. © 1979.
