Transcription Factors Include ______________

Question

Transcription factors include ______________.  
A) promoters and insulators
B) silencers and enhancers
C) activators and repressors
D) activators, repressors, and translational factors
E) enhancers and repressors

Accepted Answer

Transcription factors are proteins that bind to specific DNA sequences to control the rate of transcription of genetic information from DNA to RNA. They include activators and repressors, which respectively enhance or inhibit gene expression. Promoters and enhancers are DNA sequences that interact with transcription factors, while insulators are specialized DNA sequences that act as boundaries between different gene regions. Silencers specifically inhibit gene expression, and translational factors are proteins that interact with mRNA to control translation.
