Where Does the Regulator Bind in Order to Control Transcription

Question

Where does the regulator bind in order to control transcription?
A) Promoter
B) Operator
C) Regulator protein binding site
D) Enhancer
E) Silencer

Accepted Answer

The regulator binds to the regulator protein binding site, which is usually located upstream of the promoter sequence. This binding can either activate or repress transcription of the gene of interest. The operator is a DNA sequence that can bind to a repressor protein, which can block transcription. Enhancers and silencers are also DNA sequences that can affect gene expression, but they are not directly involved in regulating transcription through binding with a regulator protein.
