Across
  1. 4. Phage DNA is incorporated into the host cells DNA.
  2. 6. Phage causes lysis and death of the host cell.
  3. 9. Viral genetic material implanted into a host cells DNA.
  4. 12. Differentiation of colonies of desired microbes from others.
  5. 13. Cellulose cell walls, kelp, algin used in jello.
  6. 15. Death of cells > New cells. Population decreases logarithmically.
  7. 16. Production of nucleic acid and proteins.
  8. 21. Cells acquire distinct properties leading to cancer.
  9. 24. Growth slows as carrying capacity is approached. Cell death = New Cells Diminished nutrients, accumulating wastes.
  10. 26. No or little increase in number, intense metabolic activity “tooling up” for rapid growth.
  11. 29. Nutrients prepared for microbial growth.
  12. 30. The foreign Phage DNA in the host cells DNA.
  13. 32. Transform normal cells into cancerous cells.
  14. 33. Similar to selective, but designed to increase numbers of desired microbes to detectable levels.
  15. 34. Remains asymptomatic in host cell for long periods.
  16. 36. Mutated, misfolded proteins that can infect cells to continue the misfolding mutation of proteins.
  17. 38. No living microbes.
  18. 39. Infection occurs gradually over a long period; is generally fatal.
  19. 40. Exponential growth phase. Rapid reproduction, minimum constant generation time.
Down
  1. 1. Glue like substance that can found on the surface of some bacteria.
  2. 2. Raw RNA, does encode proteins, found in the human gut.
  3. 3. Mutualistic combination of green algae and fungus.
  4. 5. Nonenveloped viruses are released by…
  5. 7. Separating the viral nucleic acid from its capsid by viral or host enzymes.
  6. 8. Enveloped viruses are released by…
  7. 10. DNA or RNA, protein, and sometimes lipid.
  8. 11. Found at greater depths, agar and carrageenan( used in gummy bears). Some produce a lethal toxin.
  9. 14. Growth of chemoautotrophs and photoautotrophs; microbiological assays. These can be consistently defined.
  10. 17. Raw RNA, doesn’t encode proteins, infects plants.
  11. 18. Introduction of microbes into a medium.
  12. 19. Nucleic acid and capsid proteins assemble.
  13. 20. Genes that encode for proteins involved in normal cell growth.
  14. 22. Cellulose cell walls, gave rise to plants.
  15. 23. By receptor mediated endocytosis or fusion.
  16. 25. Viruses attach to cell membrane.
  17. 27. Platyhelminths
  18. 28. Suppression of unwanted microbes; encouraging desired microbes.
  19. 29. Growth of most chemoheterophic organisms. Can not be consistently defined due to components.
  20. 31. Nematoda
  21. 35. Growth of obligate anaerobes.
  22. 37. Microbes growing in or on a medium.
