Questions and Answers

What is the function of eukaryotic activators in transcription?

  • Inhibiting the binding of GTFs to DNA
  • Enhancing basal levels of transcription by binding to enhancers (correct)
  • Directing the starting point and direction of transcription
  • Sponsoring a low level of transcription independently

    • What is the role of gene-specific TFs called activators in eukaryotic cells?

  • Inhibiting the function of general transcription factors
  • Dictating the starting point and direction of transcription
  • Providing additional boost to transcription above the basal level (correct)
  • Sponsoring only a low level of transcription

    • How do activators enhance basal levels of transcription?

  • By interacting with both GTFs and co-activators (correct)
  • By inhibiting the function of GTFs
  • By directly binding to promoter regions
  • By independently initiating transcription

    • What dictates the starting point and direction of transcription in eukaryotic cells?
