(regulatory gene, inducer, promoter, genes of an operon, repressor, operator, operon)1. a(n) a stretch of dna consisting of an operator, a promoter, and genes for a related set of proteins, usually making up an entire metabolic pathway.2. the is/are arranged sequentially after the promoter.3. a(n) is a specific nucleotide sequence in dna that binds rna polymerase, positioning it to start transcribing rna at the appropriate place.4. a(n) codes for a protein, such as a repressor, that controls the transcription of another gene or group of genes.5. regulatory proteins bind to the to control expression of the operon.6. a(n) is a protein that inhibits gene transcription. in prokaryotes, this protein binds to the dna in or near the promoter.7. a(n) is a specific small molecule that binds to a bacterial regulatory protein and changes its shape so that it cannot bind to an operator, thus switching an operon on.
