Qbook ?54

Postby PoincareConjecture » Sat Sep 16, 2017 3:49 pm

Andrew could you clear the dust on this one step by step, thank you:); The explanation starts off well but starts to escape from me like a Philosophical construct---i am assuming the promoter genes belong to the species invaded by the Virus and the Virus would not want that hence, it hybridizes to shut that down since its interested in making its genetic material and not that of the host species is my general understanding correct?

Hi PoincareConjecture,

For this one, I think the key is to focus not on the sense/antisense issue but on the effect of the promoter sequence. There are two key facts that you have to combine to answer this question: (1) RNA complementary to a given DNA sequence will bind to it, and (2) the promoter sequence can be thought of as a 'target' to which transcription factors bind. Combining these facts, if the viral RNA binds to the promoter sequence, that will make it unavailable for the transcription factors, meaning that transcription will be reduced.

Hope this clarifies things!
