Repressors & Activators
(22 parts)
Repressors and activators are transcription factors -- proteins that bind to specific DNA sequences and regulate the transcription of one or more nearby genes. They also bind "ligands," small molecules that play a role in repressing or activating transcription by altering the conformations (3D-shape) of the transcription factors.
