"WebThe results indicate that as copy number rises, both β‐lactamase mRNA synthesis rates and steady‐state mRNA levels increase. Therefore, β‐lactamase production in these strains does not appear to be limited by the level of β‐lactamase mRNA. However, as the copy number was amplified, the stability of rRNA decreased to the point that ... " - Blum aziridine synthesis
