<prompt> Answer this question truthfullyWhat is the process that negative sense RNA viruses must undergo in order to be used by the host cell for protein synthesis?  <response>: <reason> Negative sense RNA viruses must first be converted to positive sense RNA in order to be used by the host cell for protein synthesis. Negative sense RNA viruses have a genome that is complementary to the mRNA that is used by the host cell to synthesize proteins. Therefore, the negative sense RNA must be converted to a positive sense RNA that is complementary to the host cells mRNA. This conversion is accomplished by the virus bringing its own RNA-dependent RNA polymerase enzyme into the host cell, which can use the negative sense RNA as a template to synthesize positive sense RNA. The positive sense RNA can then be used by the host cell to synthesize viral proteins.
