Study of the relative proportions of ribosomes and polysomes released by a standardized lysing procedure from isogenic RC(str) and RC(rel) strains of Escherichia coli shows that a 20-min period of amino acid starvation of RC(str) bacteria reduces the fraction of ribosomes recovered in polysomes to about 60% of its value characteristic of exponentially growing cells: A similar starvation treatment of the RC(rel) bacteria causes no appreciable reduction in the fraction of polysomal ribosomes.
对通过标准化裂解程序从大肠杆菌同基因RC(str)和RC(rel)菌株中释放的核糖体和多核糖体的相对比例进行研究表明，对RC(str)细菌进行20分钟的氨基酸饥饿处理会使多核糖体中回收的核糖体比例降至指数生长细胞特征值的约60%：对RC(rel)细菌进行类似的饥饿处理不会使多核糖体核糖体比例出现明显下降。
