WebJun 4, 2015 · The first evidence for an RNA-dependent RNA polymerase used by the virus for RNA genome replication was reported in 1962 by Baltimore and Franklin . Until then, it was believed that the genome of RNA viruses was replicated in the cell nucleus by a cellular DNA-dependent RNA polymerase. ... This virus-specific enzyme was isolated … WebOverview. Although virus replication is intimately connected to cellular processes, viruses are acellular genetic parasites that use cells to provide the systems and resources necessary for their replication. Virions are sophisticated devices for delivery of the viral genome to suitable host cells.
