Regulatory Gene (Noun)
Meaning
A gene that produces a repressor substance that inhibits an operator gene.
Classification
Nouns denoting body parts.
Examples
- The regulatory gene is responsible for controlling the expression of the operon by producing a repressor protein that binds to the operator gene.
- In the absence of the inducer molecule, the regulatory gene produces a repressor protein that inhibits the transcription of the structural genes.
- The regulatory gene was found to be a key component in the regulation of the lac operon, a genetic system that controls the breakdown of lactose in bacteria.
- When the regulatory gene is mutated, it can no longer produce the repressor protein, leading to uncontrolled expression of the operon.
- The discovery of the regulatory gene and its role in controlling gene expression revolutionized our understanding of molecular biology and gene regulation.
