    • Ocular Lens
    • Objective Lens
    • Stage
    • Light Source
    • Base
  2. What is a compound microscope?
    An objective and ocular lens is used to compound magnification
  3. Steps of a gram stain
    • Apply crystal violet dye to slide
    • Apply iodine to slide to make dye more stay-fast
    • Decolorize with alcohol to remove dye from gram negative bacteria
    • Apply safranin to slide
  4. What color does Gram positive/negative bacteria stain?
    • Positive - Blue/purple
    • Negative - Red/pink
  5. Steps to extract DNA:
    • Collect Cells
    • Lyse cells to collect DNA
    • Separate DNA from protien and debris
    • Isolate concentrated DNA
  6. What are histones, detergent and protinease K?
    • Histones - bundles that DNA are wrapped around inside the nucleus
    • Protinease K - element in lysis solution that unravels histones
    • Detergent - Breaks cell wall/membrane so DNA can be released
  7. What does the salt do while isolating DNA?
    Causes protien and other debris to clump together so DNA can be easily seen
  8. Gram positive vs. Gram negative bacteria
    • Differences in cell walls:
    • Gram positive has 20% more PTG
  9. 6 common gram positive bacteria that infect humans:
    • Streptococcus (cocci)
    • Staphylococcus (cocci)
    • Bacillus(bacilli)
    • Clostridium (bacilli)
    • Cornyebacterium (bacilli)
    • Lysteria (bacilli)
  10. Examples of Gram Negative bacteria:
    • Spirochetes - (spiral-shaped)
    • Neisseria (cocci)
  11. What is a mycoplasma?
    • A bacteria that has no cell wall.
    • Penicillins aren't effective
    • Bacteria change shape, or are "Pleomorphic"
    • Smallest bacteria capable of self-reproduction
  12. How does transcription work?
    • A - U
    • T - A
    • C - G
    • G - C
  13. What is a Type I Hypersenstitivity?
    • IgE mediated
    • Antigen causes crosslinking of IgE antibodies bound to IgE receptors of mast cells.
  14. What is a Type IV Hypersensitivity?
    • Delayed hypersensitivity
    • T-Cell mediated
    • T-Cells release cytokines
