The protein produced by Huntington's disease (huntingtin) interferes with general transcription factor (called CBP) and prevents it from binding the promoter. CBP activates genes involved in cell survival.

i) Which step in gene expression is huntingtin preventing?

ii) could this effect be produced in a prokaryote, why?

iii) In the presence of huntingtin, are the genes activated by CBP expressed? Explain

For both Sickle Cell Anemia & Huntington's Disease:

Can you copy the gene region in a human chromosome and insert it into a bacterium directly? (The tech tools to do this exist, but we don't do it that way, why?) Explain
