A. the promoter B. the operator C. lactose D. the ß-galactosidase gene E. the lactose permease gene Which of the following is not part of the lactose (lac) operon? A. the promoter B. the operator C. lactose * D. the ß-galactosidase gene E. the lactose permease gene Al osteric inhibition acts like a thermostat, turning the furnace off when heat accumulates. The product binds the enzyme, but not at the active site. Feedback regulation and regulation of gene expression are complex, multifactorial and subtle. Most genetic regulation takes place at the initiation of transcription, but this is not universal rule. Later stages of transcription can be regulated and post-transcriptional regulation is also possible. The tryptophan ( trp ) operon in E. coli the trp operon is normally on, but can be turned off. This is common in
