Expression of nucleolus organizer regions (NORs) in human acrocentric chromosomes by NSG, QFQ and RFA techniques: are they identical?
The morphology of nucleolus organizer regions (NORs) of human acrocentric chromosomes has been studied in a family by QFQ, RFA, and NSG banding techniques. The pale green colour seen by RFA was found darkly stained by NSG. However, in some instances, NOR regions were expressed by NSG technique but the pale green colour was not seen. Therefore, it is concluded that there is no direct relationship between a heteromorphism identified by one technique and that identified by another.
