Host cell ribosomes Chloroplast Cell wall Vacuole 2. Which virus is correctly paired with its method of release? Rabies virus — Binary fission Influenza virus — Budding Poliovirus — Budding Influenza virus — Cell lysis 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 Reassortment Transduction Mutation Transformation 4. 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 contain chlorophyll Because they require sunlight for replication 5. Viral capsids are composed of _________________ DNA Lipids RNA Capsomeres 6. Positive-sense (+) RNA viruses are characterized by genomes that _________________________ Can function directly as messenger RNA Must first be converted into DNA Cannot be translated by ribosomes Require reverse transcriptase before translation 7.
