Unformatted text preview: reverse transcriptase (Tortora et al., Figure 13.19) The reverse-transcribed DNA is then integrated into a host chromosome as a provirus The provirus genes can then be transcribed to provide viral mRNAs and virion genomes Alternatively, the provirus can remain latent the way the a prophage does Sometimes, integration of the provirus can cause malignant transformation of the host cell = Different RNA viruses employ a variety of (often very complicated) multiplication strategies- In contrast to phage release, release of animal virus virions does not always kill the host cell (although the cell usually dies anyway due to damage accumulated during the multiplication cycle) = Many enveloped viruses are released by budding (Tortora et al., Figure 13.20) = Naked viruses are more likely to be released by lysis of the host cell...
