Coronavirus — Negative-sense RNA Influenza virus — Positive-sense RNA Rabies virus — Negative-sense RNA Rotavirus — Positive-sense RNA 2. Viral capsids are composed of _________________ Capsomeres DNA RNA Lipids 3. ______________________ is the process where related viruses with segmented genomes co-infect the same host cell and exchange entire genetic segments, resulting in unique, hybrid viral progeny Transduction Reassortment Transformation Mutation 4. _____________________ enables a virus to attach to host cells Ribosomes Capsomeres or surface proteins Nucleic acid Mitochondria 5. Why can viruses multiply only inside living cells? Because they can survive only in water Because they lack their own metabolic and protein-synthesizing machinery Because they require sunlight for replication Because they contain chlorophyll 6.

Which cellular machinery do viruses primarily utilize to synthesize viral proteins? Chloroplast Cell wall Host cell ribosomes Vacuole 8. Positive-sense (+) RNA viruses are characterized by genomes that _________________________ Require reverse transcriptase before translation Must first be converted into DNA Can function directly as messenger RNA Cannot be translated by ribosomes 9. Which type of virus generally has a more stable genome? Viroid Retrovirus RNA virus DNA virus 10. Which virus is correctly paired with its method of release?
