Which Type of Regulator(s) Specifically Binds to Operator Regions of DNA

Question

Which type of regulator(s) specifically binds to operator regions of DNA?
A) activators
B) activators and inducers
C) repressors
D) repressors and corepressors

Accepted Answer

Repressors specifically bind to operator regions of DNA to inhibit transcription. Activators bind to specific sites on DNA called enhancers to increase transcription. Inducers are molecules that can bind to both repressors and activators to modulate their activity. Corepressors are proteins that help repressors bind to DNA and enhance their repressive activity.
