Repressor Gene

A gene that encodes a protein which can bind to an operator or promoter sequences to prevent transcription of a certain gene.

Promoter

A region of DNA that initiates transcription of a particular gene, playing a crucial role in regulating gene expression.

Operator

A segment of DNA to which a repressor protein binds, regulating the expression of genes by blocking the attachment of RNA polymerase to the promoter region.
