  1. 3. The stage in which viral DNA is inserted into a host cell's DNA and remains dormant.
  2. 5. Refers to the spread of a virus between organisms.
  3. 8. Occurs when a host cell makes thousands of copies of the viral capsid and DNA.
  4. 9. This causes changes on the protein surface of viruses.
  5. 10. Occurs when a virus injects its nucleic acid into a host cell.
  6. 11. Showed that a viral particle could reinfect an organism.
  7. 13. Nucleic acid is found here.
  8. 14. Viruses that produce a DNA copy of their RNA genes when they infect a host cell.
  9. 17. Created the first vaccine for a viral disease.
  10. 18. The cycle in which a virus infects a host, reproduces and is released to infect more hosts.

  1. 1. Occurs when an infected cell bursts.
  2. 2. Viruses that specifically invade bacterial cells.
  3. 4. Viruses need this in order to reproduce.
  4. 6. Describes how a virus attacks a specific type of cell within a specific type of species.
  5. 7. The name of the protein coat that surrounds the core.
  6. 12. This cycle includes the production of a prophage.
  7. 15. The double stranded nucleic acid found in the core.
  8. 16. Occurs when a host cell produces the viral proteins & when its own DNA begins to degrade.
