Regulator gene
Regulator Gene
A Regulator Gene (pronunciation: /ˈrɛɡjʊleɪtər dʒiːn/) is a gene that codes for a protein capable of repressing or activating the operon.
Etymology
The term "Regulator Gene" is derived from the English words "Regulator" and "Gene". "Regulator" comes from the Latin word "regulatus", which means "controlled", and "Gene" comes from the Greek word "genos", meaning "race, kind".
Function
The regulator gene produces a repressor protein that binds to the operator gene, thereby preventing the transcription of structural genes. It plays a crucial role in the gene expression and genetic regulation.
Related Terms
- Operator Gene: A segment of DNA to which a repressor protein binds. It is part of the same operon as the regulator gene.
- Repressor Protein: A protein produced by the regulator gene that binds to the operator gene to prevent gene transcription.
- Gene Expression: The process by which information from a gene is used to synthesize a functional gene product.
- Genetic Regulation: The process by which a cell determines which genes it will express and when.
