Abstract excerpt
The genomic activity and polymorphisms of nucleolus organizer regions (NORs) were studied in an individual with routinely used AgNO3 and Q-banding techniques. The results demonstrate that (a) the mean number of NORs per metaphase spread was 7.4, (b) chromosomes 14, 13, 15, and 21 showed variations of Ag-NOR in decreasing order, (c) chromosome 22 did not show a polymorphism in any cell examined, and (d) both...
