    • List, in order, the six general steps of virus reproduction.
    • Explain how enveloped viruses acquire their envelopes.
    • Compare and contrast the reproduction of DNA viruses and RNA viruses.
    • Describe the two possible locations for the viral genetic material within the host cell.
    • Distinguish between lytic and lysogenic viruses based on location of the viral genome with respect to the host genome and the effects on the host cell.
    • Describe + sense and – sense RNA with relation to mRNA.
    • Explain  the roles of HA and NA in influenza infection.
    • Differentiate between antigenic shift and antigenic drift in influenza and explain how these contribute to seasonal and epidemic flu outbreaks.
    • Describe the three general methods by which viruses can be detected, focusing on the evidence of viral presence which is being detected (not the intricacies of the lab techniques)
    • Explain at least 3 mechanisms by which a virus can be oncogenic (not going to be covered Sp21)
    • Given a description of a virus and its mechanism of reproduction, determine its potential for being oncogenic (not going to be covered Sp21)
