Genes are expressed all of the time. activator constitutive inducible repressed clustered

Constitutive is the answer to your question because regulation of bacterial gene expressed occurs primarily at the level of transcription. Genes are often clustered in operons. These genes can be expressed at all times in the cell (constitutive genes) or they can be under the control of repressor and/or activator proteins (inducible genes
