Across
  1. 1. a virus cannot reproduce without invading a host cell and using its resources
  2. 7. areas in a culture where cells have been destroyed due to viral infection
  3. 8. when the entire virus gets engulfed by the host cell as a method of infection
  4. 10. an enzyme that can synthesize DNA from RNA
  5. 11. a type of virus that can permanently alter a host cell's genetic material, causing tumor cells
  6. 12. a 20-sided figure. One of the two different capsid structures a virus may have
  7. 16. naked piece of RNA that infects animals
  8. 17. when a bacterial host cell carries bacteriophage DNA in order to be copied and passed down during normal cell division
Down
  1. 2. damage to a host cell caused by a virus
  2. 3. repeating units of protein molecules that make up the capsid
  3. 4. a membrane common for viruses that infect human cells. It is made of the same materials as the host cell which allows the membranes to fuse
  4. 5. a fully formed virus capable of infecting a host cell
  5. 6. when a virus binds to the receptor sites on the cell membrane of a host cell
  6. 9. when viral DNA is incorporated into the DNA of the animal host cell
  7. 13. protein shell that surrounds the nucleic acid of a virus
  8. 14. the limitation of hosts a virus can infect based on whether they have complementary receptors
  9. 15. naked piece of RNA that infects plants
