核仁组成区(NOR)是位于某些染色体上特殊部位的核糖体基因(rDNA),通过其转录而合成核糖体RNA(rRNA),在蛋白质合成中起极其重要作用”。NOR银染法为研究瘤细胞核仁的结构和功能改变,为探索细胞增生和分化的基因调控提供了
The nucleolar organizing region (NOR) is a ribosomal gene (rDNA) that is located on a specific site on certain chromosomes and synthesizes ribosomal RNA (rRNA) through its transcription and plays an extremely important role in protein synthesis.” NOR silver staining is To study the structural and functional changes of the nucleolus of tumor cells to provide a basis for the exploration of gene regulation of cell proliferation and differentiation
