Operator Gene (Noun)
Meaning
A gene that activates the production of messenger RNA by adjacent structural genes.
Classification
Nouns denoting body parts.
Examples
- The operator gene played a crucial role in the transcription process, controlling the expression of nearby structural genes.
- In the regulatory system, the operator gene is bound by a repressor protein, inhibiting the transcription of downstream genes.
- Genetic mutations can occur in the operator gene, disrupting its ability to regulate the expression of adjacent structural genes.
- The Lac operon is a classic example of an operon system that includes an operator gene, which controls the transcription of nearby genes involved in lactose metabolism.
- Researchers have identified several types of operator genes involved in different operon systems, each with unique regulatory functions and mechanisms of action.
