What is the function of eukaryotic activators in transcription?
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?
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?
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
