Lethal mutagenesis is a promising new antiviral therapy that kills a virus by raising its mutation rate . One potential shortcoming of lethal mutagenesis is that viruses may resist the treatment by evolving genomes with increased robustness to mutations . Here , we investigate to what extent mutational robustness can i... | The high mutation rate of RNA viruses , such as HIV , allows them to rapidly evolve resistance to host defenses and antiviral drugs . A new approach to treating these viruses—lethal mutagenesis—turns the mutation rate of these viruses against them . It uses mutagens to increase the viruses' mutation rates so much that ... | [
