How to Extract DNA from Kiwi - Core Practical

  1. Use pestle and mortar to crush the kiwi - this breaks up the cell wall
  2. Add water, salt (DNA is insoluble to salt water but not water - makes sure it doesn’t dissolve, and salt also breaks through cell wall) and washing up liquid to a beaker (which breaks up the cell membrane and parts of the nucleus)
  3. Stir slowly until salt is dissolved
  4. Add kiwi to mixture
  5. Put beaker in hot water bath 
  6. Filter solution
  7. Drizzle ice cold ethanol around the beaker to attract (idk if thats the right word) the DNA which will look like limescale
  8. Use glass rod to lift out the white substance
