The transcription of genetic information into RNA is the first step in gene expression that precedes translation, the process of decoding RNA into proteins.
WebRifamycin is a group of antibiotics whose activity depends on its high affinity for prokaryotic RNA polymerase inhibiting bacterial DNA-dependent RNA synthesis (Calvori et al., 1965 ). Rifamycins can enter neutrophils and macrophages and then inhibit bacterial DNA-dependent RNA polymerase ( www.amrls.cvm.msu.edu ).
