A Newly- Discovered Double- Stranded RNA Virus Which Infects Animal

question 47

Multiple Choice

A newly- discovered double- stranded RNA virus which infects animal cells is found to contain a unique enzyme which synthesizes double- stranded RNA using an RNA template. Which of the following statements is likely to be true?

• A) This enzyme would not be a good antiviral drug target as the host cell likely has a similar enzyme which could be affected by such a drug.
• B) The enzyme probably came from the host animal cell and is coded for by a gene in the host cell.
• C) This enzyme is coded for by a gene in the host cell.
• D) The enzyme probably came from the host animal cell.
• E) The virus must bring this enzyme into the host cell as synthesizing RNA from an RNA template does not happen in animal cells.
