Positive Gene Regulation

Definition

Positive gene regulation refers to a mechanism in which certain proteins such as activators bind to regulatory regions of DNA, leading to increased transcriptional activity and production of mRNA from specific genes.

A protein that binds to regulatory regions of DNA and prevents or decreases transcriptional activity.

Transcription Factors:

Proteins that play a crucial role in regulating gene expression by binding to specific sequences on DNA and controlling when genes are turned on or off.

Gene Expression:

The process by which information encoded in genes is used by cells for synthesizing functional proteins.
