Electron microscope observations show in the primary nucleolus some granulations with dimensions less 70 A than those of the amphinucleoli (90 A). Even though the primary nucleolus has a high RNA content, this has not a very active turnover except at the periphery, probably in relation to the emission of 'daughter-nucleoli'. The amphinucleoli, even though they do not have RNA which is cytochemically discloseable, possess, however, RNA at a very high rate of turnover.
电子显微镜观察显示，初级核仁中有一些颗粒，其尺寸比双质核仁（90埃）小70埃。尽管初级核仁的RNA含量很高，但除了在周边区域外，其周转并不活跃，这可能与“子核仁”的释放有关。双质核仁虽然没有细胞化学可显示的RNA，但却以非常高的周转率拥有RNA。
