key term - Gene Regulation

Definition

Gene regulation refers to the control of gene expression, determining which genes are turned on or off in response to internal and external signals. It is crucial for cellular processes such as development, homeostasis, and adaptation.

Promoters:

These regions of DNA signal the starting point for transcription and play a critical role in initiating gene expression.

Enhancers:

Enhancers are stretches of DNA that increase the likelihood of gene expression by binding specific proteins.

Epigenetics:

This field studies heritable changes in gene activity without altering the underlying DNA sequence itself. It involves modifications like DNA methylation and histone acetylation that affect how genes are regulated.
