I s (super repressor ) Repressor cannot bind lactose; thus, it cannot be released from the operator site.
WebWhen glucose is present, the lac operon is inhibited. One reason that regulation of gene expression is important is that it saves energy and materials from being used when they are not needed. At which point would regulation be most efficient in conserving energy and materials if the product of a gene is not needed?
WebJul 7, 2024 · The lac operon exhibits both systems. It is a negative control system because expression is typically blocked by an active repressor (the lac repressor) that turns off transcription. The lac repressor binds to the operator region and negatively controls (prevents) transcription.
