True. Some bacterial cells are resistant to a variety of antimicrobials because they actively pump the drugs out of the cell.
A significant resistance mechanism in Gram-negative bacteria is drug efflux. It expel solutes from the cell. Antimicrobials and metabolites are just a few of the hazardous compounds that Efflux pumps help bacteria remove from their interior environments so they can regulate it.
The main efflux systems in Gram-negative bacteria are members of the RND superfamily and typically consist of an outer membrane protein channel, a periplasmic protein, and a cytoplasmic membrane pump. The most common example is MFS (such as Bmr and Blt in Bacillus subtilis) and the ABC transporters.

Transcription is important to genetic information. If there is an error during the transcription process, the DNA copies would not be accurate, causing the proteins to be improperly assembled, or not assembled at all.
