  4. 3. Word Splash • Having a multiple of the normal chromosome number • Plants work better when they have this • Instead of 9 Chromosomes, there could be 18, 27, etc.

  6. 5. Word Splash • Placing a mixture of DNA into a gel and applying an electric current. • DNA is then separated according to size. • You will be doing a Virtual Lab on this Today

  7. 6. Word Splash • Used to make multiple copies of a segment of DNA or gene • Developed by Kary Mullis • After only 6 copies, you can have up to 64 DNA segments

  8. 7. Word Splash • When a cell (usually a bacteria) takes in DNA from outside the cell • Example: Griffith’s rats
