Question 7

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?

Accepted Answer

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.
