Question 3

A clinical virologist is examining a newly isolated pathogen. Before confirming its taxonomic classification as a virus rather than a prokaryote, they analyze its macromolecular components and replicative capacity.

a.

Identify two structural components that are common to all virus particles, and describe the specific biological role of one of these components.

[2]
b.

Unlike prokaryotic cells, viruses are described as both acellular and non-living. Explain the precise biological meaning of these two terms.

[2]
c.

The researcher considers treating a patient infected with this pathogen using a beta-lactam antibiotic, which prevents bacterial peptidoglycan synthesis. Explain why this class of antibiotic is completely ineffective against viruses.
