Briefly explain why antibiotics do not have an effect on viral infections (e.g. influenza).  To get full credit, you must show that: (1) you’re familiar with at least one of the specific mechanisms of how a particular antibiotic works (name the antibiotic, the enzyme it targets, and how disrupting this enzyme affects the bacteria), and (2) you can relate this to the processes involved in viral replication. Note that this question is not asking about selective toxicity. It is asking about why antibiotics don’t work against viruses.
