Abstract
The expression of ribosomal cistrons in the nucleolar organizer regions (NORs) has been studied with high resolution banding in the acrocentric chromosomes of 10 normal individuals. It was found that if a particular chromosome did not stain with silver nitrate at metaphase, then it did not stain at prophase either. Therefore, it is concluded that some of the acrocentric chromosomes have variable expression of NORs.
摘要
在10名正常个体的近端着丝粒染色体中，利用高分辨率显带技术研究了核仁组织区（NORs）中核糖体顺反子的表达。结果发现，如果某一特定染色体在中期不被硝酸银染色，那么它在前期也不被染色。因此，可以得出结论，一些近端着丝粒染色体的NORs存在可变表达。
