Lactose Repressor

The lactose repressor is a protein that binds to the promoter region of the lactose operon in bacteria, regulating the metabolism of lactose by inhibiting the transcription of lactose-utilizing genes.

Transcription

The process in which the DNA sequence in a gene is copied into mRNA, serving as the first step in gene expression.

Lactose Operon

A gene regulatory mechanism in bacteria that allows the cells to adapt to the presence of lactose, enabling the digestion of this sugar when it is available.

Negative Control
