Medium which has been dialyzed against a dense population of Tetrahymena cells contains a factor which reduces the rate of RNA synthesis in other Tetrahymena cells inoculated on that medium. Furthermore, this extracellular factor inhibits the ribosomal RNA synthesis in vitro when added to an RNA synthesizing r-chromatin preparation.
已针对大量四膜虫细胞进行透析的培养基中含有一种因子,该因子会降低接种在该培养基上的其他四膜虫细胞中的RNA合成速率。此外,当将这种细胞外因子添加到RNA合成的r - 染色质制剂中时,它会在体外抑制核糖体RNA的合成。
