True or False: viruses can be classified as prokaryotic or eukaryotic - False. Viruses are neither prokaryotic or eukaryotic What is an obligate intracellular parasite? - viruses cannot replicate unless inside a living host cell. As a parasite, a virus depends on its living host to provide the framework (proteins, etc) to replicate—to make additional copies of itself. What is a viral capsid? - a membrane-like protective structure that contains genetic material similar to nucleus of eukar...
