Which of the following statements is true regarding enhancers and silencers? A) They interact with regulatory transcription factors. B) Enhancers decrease transcription rates. C) Silencers are involved in promoting transcription. D) Both are types of transcription factors.
Understand the Problem
The question is asking about the characteristics and functions of enhancers and silencers in the context of gene regulation, specifically which statement among the provided options accurately describes their roles.
Answer
They interact with regulatory transcription factors.
The final answer is A) They interact with regulatory transcription factors.
Answer for screen readers
The final answer is A) They interact with regulatory transcription factors.
More Information
Enhancers and silencers are regulatory DNA sequences that bind to regulatory transcription factors to either increase or decrease transcription rates. Enhancers activate transcription, whereas silencers repress transcription.
Tips
A common mistake is confusing enhancers with silencers, attributing them the wrong function of transcription modulation.
