A scientist compares the promoter regions of two genes. Gene A’s core promoter plus proximal promoter elements encompasses 70bp. Gene B’s core promoter plus proximal promoter elements encompasses 250bp. Which of the scientist’s hypotheses is most likely to be correct? More transcripts will be made from Gene B Transcription of Gene A involves fewer transcription factors Enhancers control Gene B’s transcription Transcription of Gene A is more controlled than transcription of Gene B.

8 There is a promoter of a tumour suppressor gene in a mutant cancer cell line, and discover that instead of a nucleosome free region 5’ of the transcription start site there are nucleosomes bound. What would be the likely consequence on transcription of this gene? I am not sure about what is the outcome, normally it binds to the nucleosome free region 5' of the transcription start site to initiate transcription. Now, it binds with nucleosomes. What will happened? Is the DNA cannot transcripted successfully? Due to the transcription needs a naked DNA to process while in nucleosomes, DNA has been wrapped up. Thank you.

1. Eukaryotic transcription initiation begins at the TATA site approximately 30 bp upstream of the transcription start site. One subunit of TFIID (Transcription Factor II D) binds at the TATA site. What is this subunit? 2. This initial binding at the TATA site is specific and coincides with the binding of the entire TFIID complex. This results in a massive change of shape to the DNA helix of the promoter region. After TFIID binding and this shape change, another GTF(General Transcription Factor) can bind. What is this next GTF? 3. Next, which GTF binds to a DNA sequence in the promoter region and to the TFIID-promoter complex before the binding of the RNA Pol II-TFIIF complex? 4. Describe how would you redraw Figure 13-16 to reflect the change in the dsDNA helical shape due to the initial binding to the TATA site? 5. What other…
