Chapter 15, Problem 12RQ

How do enhancers and promoters differ?

  1. Enhancers bind transcription factors to silence gene expression, while promoters activate transcription
  2. Enhancers increase the efficiency of gene expression, but are not essential for transcription. Promoter recognition is essential to transcription initiation.
  3. Promoters bind transcription factors to increase the efficiency of transcription. Enhancers bind RNA polymerases to initiate transcription.
  4. There is no difference. Both are transcription factor-binding sequences in DNA.

Students have asked these similar questions
Enhancers contain binding sites for transcription factors that regulate transcription. are activators that act across insulator barriers. contain binding sites for the basal transcription apparatus. are necessary for transcription, but are not involved in regulating transcription.
What is the role of general transcription factors? GTFs bind to enhancers or silencers and regulate transcription GTFs bind to the core promoter and allow transcriptional initiation GTFs are cis-acting regulatory sequences GTFs regulate the length of the mRNA GTFs are part of the RNA polymerase II holoenzyme, and control transcription initiation
Below is a model of a signal transduction pathway that results in the transcribing of mRNA: Receptor protein Transcription factor Phosphorylation cascade DNA mRNA What is the best description of what would happen if the phosphorylation cascade resulted in a phosphate being attached to the transcription factor? O mRN would not stop being transcribed from the DNA. O The phosphorylation cascade would continue to release excess phosphates. O mRNA would stop being translated from the DNA. O Receptor proteins would not bind to the signaling hormone.
