- 10. is a preparation of weakened or killed pathogens or inactivated toxins
- 14. spherical prokaryotes
- 15. HIV belongs to a group of RNA viruses
- 17. block the growth and reproduction of bacteria
Down
- 1. bacteriophage DNA that becomes embedded in the bacterial host's DNA
- 2. infection a virus enters a bacterial cell, makes copies of itself, and causes the cell to burst or lyse
- 3. is a non-living particle made of proteins, nucleic acids, and sometimes lipids
- 5. the protein coat surrounding a virus
- 7. unicellular organisms that lack a nucleus
- 8. many prokaryotes exchange genetic information
- 9. rod-shaped prokaryotes
- 11. infection which a host cell is not immediatly taken over,some bacteria viruses cause this
- 12. disease an unknown disease that appears in a population for the first time or a well-known disease that suddenly becomes harder to control
- 13. fission when a prokaryote has grown so that is has nearly doubled in size, it replicates its DNA and divides in half, producing two identical cells
- 16. when growth conditions become unfavorable, many prokaryotic cells
