A clinical research team is studying the transmission of a newly isolated respiratory pathogen. Microscopic analysis confirms that the pathogen is viral rather than bacterial.
State two structural components that are common to all virus particles, and describe the specific function of one of these components.
In biological classification, viruses are described as being both 'acellular' and 'non-living'. Explain what is meant by each of these two terms.
Explain why treatment with antibiotics like penicillin, which inhibit peptidoglycan cell wall synthesis, or erythromycin, which inhibits bacterial translation, has no therapeutic effect against viral infections.
