If RNA extracted from a virus was injected into a host cell the cell will not begin to make new viruses.?

If RNA extracted from a virus is injected into a host cell, the cell may begin to produce new viruses, provided the RNA is infectious and the host cell has the necessary machinery to translate and replicate the viral RNA. For many RNA viruses, the injected RNA can serve as a template for translation into viral proteins and for replication of new viral genomes. However, if the RNA is non-infectious or lacks necessary elements for translation and replication, the host cell will not produce new viruses.
