Replication of many RNA viruses depends on RNA polymerase. The antiviral drug ribavirin does not inhibit the polymerase but instead increases its error rate. Explain how this affects the virus.
The first electron micrograph of a virus (tobacco mosaic virus) was produced in 1939. Before that time, how did scientists know that viruses existed if they could not see them? (Hint: Early scientists called viruses “filterable agents.”)
Which statement is true of viral replication? In the process of apoptosis, the cell survives During attachment, the virus attaches at specific sites on the cell surface The viral capsid helps the host cell produce more copies of the viral genome mRNA works outside of the host cell to produce enzymes and proteins.

HersheyChase Experiments The graph shown in FIGURE 8.5 is reproduced from an original 1952 publication by Hershey and Chase. Bacteriophage were labeled with radioactive tracers and allowed 10 infect bacteria. The virusbacteria mixtures were then whirled in a blender to dislodge any viral components attached to the exterior of the bacteria. Afterward, radioactivity from the tracers was measured. FIGURE 8.5 Detail of Alfred Hershey and Martha Chases 1952 publication describing their experiments with bacteriophage. Infected bacteria refers to the percentage of bacteria that survived the blender. How did the researchers know that the radioisotopes in the fluid came from outside of the bacterial cells and not from bacteria that had been broken apart by whirling in the blender?
