Question 5: (5 marks) Mediator is a protein complex that is able to act as a bridge between transcriptional activators and the TFIID-dependent RNA Pol II machinery. Draw what you would expect the promoter region to look like with Mediator acting at the promoter of a gene with an E-box 3000bp upstream of the transcriptional start site, which requires TCF4 for activation of transcription....

The process of DNA transcription: produces single stranded RNA complementary to the coding strand. requires RNA polymerase. is discontinuous. produces double stranded DNA. requires DNA polymerase III. Among the significant sites that many eukaryotic promoters contain is: a TATAAT box near –10. a TATA site near –30 to –100. a CATA site at the transcription start site. a Pribnow box. the Shine-Dalgarno sequence.

Which of the following accurately describes the promoter of a gene? a) It is the place on the DNA where RNA polymerase binds. b) It determines which DNA strand of a gene is used as a template. c) It is the first region of DNA that is transcribed into RNA. d) both a and b I think the answer is A but I'm not positive. C cannot be correct because the promoter does not get transcribed, and I don't think...
