Virology Exam #1 Properties of a virus - correct answer - Filterable agents (not retained in a filter like bacteria are) - Obligate intracellular parasites - Cannot make energy or proteins independent of a host cell (no generation of metabolic energy) - Viral components are assembled and do not replicate by "division" - Must encode any required process not provided by the host cell - Genomes may be RNA or DNA but not both - Have a naked capsid or envelope morphology Theories on how v...

What are the components common to all virions? Choose one or more: A. envelope B. capsid C. DNA or RNA genome D. DNA and RNA genomes correct answersB, C Yes, virions are highly efficient particles requiring only a viral capsid and either an RNA or DNA genome, but never both. Identify the function(s) of the viral capsid. Choose one or more: A. is necessary for RNA virus attachment B. contains virulence factors that increase the severity of viral disease C. protects the viral genome ...

Virology Exam 1 (Columbia - Racaniello) Exam Questions and Answers 1. How many viruses do we carry at any given time? Why don't these make us sick? - Answer-- most viruses just pass through us - non-human viruses - Viruses can be beneficial (thermotolerant fungi) - Strong immune system! How can viruses be beneficial?
