What will happen when bacterial cells that contain the pARA-R plasmid are not given arabinose?

When bacterial cells containing the pARA-R plasmid are not given arabinose, the expression of the gene controlled by the arabinose promoter will be suppressed. This means that the proteins or traits encoded by that gene will not be produced, as the necessary transcription factors that activate the promoter in the presence of arabinose will not be present. As a result, the bacteria will not exhibit the characteristics or functions associated with the gene in question.
