ABSTRACT Nucleolar organizer regions(NORs) are loops of DNA included ribosomal genes that ribosomal RNA translated of it, which synthesis proteins. NORs are in short arms of acrocentric chromosomes and associated with argyrophilic proteins, which are seen as black dots, termed “AgNOR”, by using colloidal silver (Ag) staining method. AgNOR count in nucleous have direct relation with cel...
