Fig. 4: Replication of a Double-Stranded
RNA Viral Genome and Production of Viral mRNA
To replicate the viral
genome, RNA-dependent RNA polymerase enzymes copy both the (+) RNA and (-) RNA
strands of the genome producing a dsRNA genomes.
To produce viral mRNA
molecules. RNA-dependent RNA polymerase enzymes copy the (-) RNA strand into
(+) viral mRNA. The (+) viral mRNA can then be transtated into viral proteins
by host cell ribosomes.
