RNA-dependent RNA polymerases (RdRp) are critical to the replication of RNA viruses.<ref>DOI:10.1038/s41598-018-22328-3</ref> Due to this protein's importance in the viral life cycle, they are feasible targets for vaccine development.<ref>DOI:10.1038/s41598-018-22328-3</ref> Inhibition of RdRp results in the inhibition of transcription of the viral genome, ultimately resulting in no new production of virions for the virus. | RNA-dependent RNA polymerases (RdRp) are critical to the replication and transcription of RNA viruses.<ref>DOI:10.1038/s41598-018-22328-3</ref> Due to this protein's importance in the viral life cycle, they are feasible targets for vaccine development.<ref>DOI:10.1038/s41598-018-22328-3</ref> Inhibition of RdRp results in the inhibition of transcription of the viral genome, ultimately resulting in no new production of virions for the virus. | ||
