  1. What is gel electrophoresis?
    DNA is cut up to pieces by restriction enzymes.
  2. What moves DNA pieces through a gel?
    electric current/.
  3. what happens to small/ large pieces?
    small pieces move fast, big ones move slow.
  4. how do you visual the DNA on a gel?
    by stains.
  5. What is DNA fingerprinting?
    the patterns of the bands.
  6. what are some uses for DNA finger printing?
    • indentify family members
    • indentify missing person
    • indentify parts of bodies
    • trace orgin of diseases
  7. what are the tools used for DNA fingerprinting? (6)
    • micropipets
    • stains
    • DNA
    • aragose gel

  8. Micropipet?
    what are the necessities?
    • percision instrument for measuring VERY small volumes.
    • always use a tip; always keep vertical
  9. stains and DNA
    where are the DNAs kept at?
    • stains DNA.
    • epitubes.
  10. agarose gel
    made of carbohydrates. DNA is pipetted into wells.
  11. tanks
    have platform for gel. two reservoirs of water. + and - electro.
