    Included Quiz Questions

    1. dsDNA
    2. Gapped dsDNA
    3. Linear ssDNA
    4. Circular ssDNA
    1. Positive sense single stranded RNA genomes may be translated directly by the host cell ribosome to make viral protein.
    2. Double stranded RNA genomes can be directly translated to make viral protein by ribosomes.
    3. The positive sense RNA strand of a double stranded RNA virus has the sole purpose of serving as a template for viral replication.
    4. RNA genomes can be copied by host cell RNA-dependent RNA polymerases.
    5. Positive sense single stranded RNA virus replication cycles do not require a negative strand intermediate.
    1. A modern validation of the Hershey-Chase experiment
    2. Introduction of viral proteins into cells
    3. Production of infectious virus after transformation of cells by viral DNA
    4. A way to make clonal virus stocks by plaque assay
    5. A way to make mutations by treating viruses with ultraviolet light
