RNA pol I RNA pol II RNA pol III RNA pol IVRemdesivir is an antiviral drug used to treat SARS-CoV-2 infections. It is a broad-spectrum antiviral, meaning it has activity against many different viruses. Remdesivir can be incorporated into a new RNA chain as a virus replicates and can interfere with the viral replication machinery. Template RNA Elongation New RNA SARS-CoV-2 RNA polymerase Template groove Nucleotide entrance Nucleotides Remdesivir Figure 1. A representation of remdesivir and the viral replication machinery for SARS-CoV-2. 6. Figure 1 shows that remdesivir "mimics” an important component of RNA replication. Which specific component of RNA replication has a structure like that of remdesivir? 7. Propose a hypothesis about how remdesivir might inhibit the virus's replication process.
