Abstract excerpt
In merodiploid cells containing a double dose of structural genes of RNA polymerase subunits--rpoB and rpoC--the rate of synthesis of beta- and beta'-subunits is 2 times higher than in haploid cells. Missense mutation rpoC1 (tsX) in the beta'-polypeptide gene accelerates the synthesis of both beta- and beta'-subunits, particularly at a nonpermissive temperature. When rpoB-rpoC operon containing mutation rpoC1 is...
