Fig. 10A: Replication of a Double-Stranded DNA Viral Genome and production of Viral mRNA

To replicate the viral genome, DNA-dependent DNA polymerase enzymes copy both the (+) and (-) DNA strands producing dsDNA viral genomes.

To produce viral mRNA molecules. DNA-dependent RNA polymerase enzymes copy the (-) DNA strand into (+) viral mRNA. The (+) viral mRNA can then be transtated into viral proteins by host cell ribosomes.
