Storyboard Text

  • The DNA extraction lab started with my group me Aric and Tyler putting our goggles and aprons on for safety purposes.
  • The first thing we did was go collect our strawberry in a bag and let the air out of the bag. You  release the air from the bag so the bag does not pop and make a mess.
  • The next thing we did was smashing the strawberry to break the cell wall which releases the DNA so we can then extract that DNA
  • Than we poured dna extraction fluid from a 10 ml graduated cylinder which included   soap to break down the lipid bilayer of the cell membrane and salt used to make DNA less water soluble in the bag and mashed and mixed it up for 5 minutes.
  • Next we put a cheese cloth with water on it in a filter to stop chunks of strawberry from going into the test tube than we let the strawberry juice and dna drip down the filter and into the test tube.
  • After that you put alcohol in the test tube and the dna starts floating up into the clear alcohol making it visible. The alcohol also makes the DNA waterproof
