Q: RNA-dependent RNA polymerase catalyzes the replication of RNA from an RNA template as opposed to the typical DNA-dependent RNA polymerase present during gene transcription. Many human RNA viruses require RNA-dependent RNA polymerases to replicate their genomes. This polymerase must be encoded by the virus itself; it cannot be sourced from the host. The reason for this is that
A		human RNA-dependent RNA polymerase is incompatible with viral RNA
B		human RNA-dependent RNA polymerase will recognize viral RNA as foreign and trigger an immune response.
C		human RNA-dependent RNA polymerases will degrade rather than replicate viral RNA.
D		humans lack RNA-dependent RNA polymerases.
