You have isolated a newly discovered virus and are attempting to characterize it. You begin with its genome. First, you isolate the viral genome and find that it is single stranded. Then, you isolate the virion-producing mRNA from cultured cells infected with the virus and find that the mRNA is complementary to the genome. Based on this information, you conclude that ...

    This virus has a negative-sense genome.

    Explanation:

    1. As given here, the virus is single stranded. Viruses use host machinery for their replication and other processes.

    2. Virus first makes multiple copies of DNA according to its genome, by using the host machinery. Then this DNA is transcribed into mRNA and other RNA.

    3. As given, this mRNA is complementary to the genome, by this information, we can conclude that this virus has a negative-sense genome.
