Sample Question16.1) The national regulatory body overseeing the transport of biohazardous material in your country has asked you to provide an expert opinion concerning the safety level of an engineered composite virus that needs to be shipped from one laboratory to another. The virion in question possesses a capsid derived from human papillomavirus that contains rotavirus dsRNA and an influenzavirus RNA-dependent RNA polymerase. The nucleocapsid is surrounded with an envelope containing Ebola virus GP spikes. If this virion were to infect permissive cells, which kind of virus would be generated?
