Abstract
The relative transcriptional activities of genes coding for ribosomal RNA (rRNA) and ribosomal proteins (r-proteins) at a steady-state growth rates ranging from 0.65 to 2.1 doublings/h can be estimated from previous measurements of the synthesis rates of stable and unstable RNA (Pato & von Meyenburg, 1970; Nierlich, 1972a,b; Bremer et al., 1973; Dennis & Bremer, 1973b, 1974b) and ribosomal proteins (Schleif, 1967; Dennis & Bremer, 1974a). Comparison of these transcriptional activities suggests that the expression of the r-protein genes and rRNA genes is controlled seperately.
摘要
在0.65至2.1次倍增/小时的稳态生长速率下，编码核糖体RNA（rRNA）和核糖体蛋白（r蛋白）的基因的相对转录活性，可以根据先前对稳定和不稳定RNA（Pato和von Meyenburg，1970；Nierlich，1972a、b；Bremer等人，1973；Dennis和Bremer，1973b、1974b）以及核糖体蛋白（Schleif，1967；Dennis和Bremer，1974a）合成速率的测量来估算。这些转录活性的比较表明，r蛋白基因和rRNA基因的表达是分开控制的。
