repressor gene Sentence Examples
- Lac repressor gene is responsible for the regulation of lactose metabolism in bacteria.
- The repressor gene controls the expression of genes involved in the synthesis of a specific enzyme.
- Mutations in the repressor gene can lead to overproduction or underproduction of the regulated enzyme.
- The repressor gene product, the repressor protein, binds to the operator region of the regulated genes.
- When bound to the operator, the repressor gene blocks RNA polymerase access to the promoter region.
- This binding represses transcription of the regulated genes, preventing their expression.
- In the absence of the inducer, the repressor gene keeps the regulated genes turned off.
- When the inducer is present, it binds to the repressor gene and causes a conformational change.
- This conformational change weakens the repressor binding to the operator, allowing RNA polymerase to access the promoter.
- The repressor gene thus acts as a molecular switch, controlling the expression of the regulated genes in response to a specific environmental signal.
