You have isolated a newly discovered virus and are attempting to characterize it. You begin with its genome. You first isolate the virion-producing mRNA from cultured cells infected with the virus. When you compare this mRNA to the viral genome, you find that they are complementary. What does this tell you?
A) This virus has a positive-sense genome.
B) This virus has a negative-sense genome.
C) This virus has an ambisense genome.
D) The virus does not use DNA or RNA.

You have isolated a newly discovered virus and are attempting to characterize it. You begin with its genome. In the given case.

This virus has a negative-sense genome.

Hence, Option B is correct.

  • All of an organism's genetic material is contained in its genome. It contains genes and other components that regulate the function of those genes, and it is composed of DNA (or RNA in some viruses).
  • As we discovered in the above example, there are three genome types that exist since the mutation is A–G: AA, AG, and GG.
  • The GG type of these three genome types has the most anti-alcohol activity, whereas the AA type has the least activity and can barely digest alcohol.
