Preparing samples to be sent to be sequenced by PNACL

Repeating the combustion experiment

  • Blocks of both DNA and no DNA coating were made
  • Blocks are thicker than last experiment to observe the difference
  • Both DNA and no DNA blocks were sprayed with water and dried for equal treatment conditions

Second attempt at polystyrene combustion with DNA

  • Larger strips were used
  • DNA was spread on some and water was spread on some other
  • Strips were left to dry on the bench
  • some strips were cut from a block of polystyrene which was made with DNA
  • Each strip was burnt with a bunsen burner with a ruler and filmed to compare the rate of burning
  • Results were not as expected, DNA appeared to make no difference except a blacker remnant
