Which of the following is FALSE regarding regulation of gene expression in bacteria?
◦ There can be transcriptional regulation for the initiation and the amount of transcription, as well as post-transcriptional regulatory mechanisms.
◦ Regulated transcription is necessary; constitutive transcription, continuously transcribing genes with no regulatory control, does not occur without mutation.
◦ Negative control of transcription involves the binding of a repressor protein to a regulatory DNA sequence, with the consequence of preventing transcription.
◦ Positive control of transcription involves the binding of an activator protein to a regulatory DNA sequence, with the result of initiating transcription.
◦ Repressor proteins commonly contain DNA-binding and allosteric domains.
