What basal transcription factor is most often affected by regulatory transcription factors?

Question

Quizplus · Accepted Answer

TFIID is the basal transcription factor that is most often affected by regulatory transcription factors. This is because TFIID is the first factor to bind to the promoter region of the DNA and recruits other basal transcription factors to initiate transcription. Regulatory transcription factors can interact with TFIID and modify its activity, leading to changes in gene expression. TFIIB, TFIIE, and TFIIF are also basal transcription factors, but they are not as frequently targeted by regulatory transcription factors as TFIID.
