Question

Which viral genome is likely to require an RNA-dependent RNA polymerase for transciption upon viral entry?

Answer 1

Answer:

(-) sense single-stranded RNA

Explanation:

Negative sense refers to viruses that use the negative sense single stranded RNA as their genetic material.

It is essential for the negative viral strand is complimentary to the mRNA so it is converted to a positive RNA by RNA polymerase.  

Negative sense single stranded RNA virus require an RNA dependent RNA polymerase for transcription.  This is because it essential in encoding proteins by catalyzing the complimentary RNA strand to the given RNA tempelate.
