these results demonstrate ( i ) that regulation of the synthesis of the beta- and beta-rna polymerase subunits is under these conditions primarily transcriptional rather than translational , and ( ii ) that a stimulation of rpob and c gene expression results from a restriction on rna synthesis caused by either rna polymerase inactivation or inhibition of its assembly .
