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