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 ) .
