OBSERVATIONS
Various DNA sources using -15°C alcohol
Strained & unstrained kiwi
Different parts of the leek plant
Various DNA sources using 4.5°C and 21.5°C alcohol
Wheat germ extraction
Adding meat tenderizer to the source
I also prepared slides from the onion and pea DNA extractions and looked at them under a microscope. Because the extraction contains millions of DNA strands, you cannot see the helix. I also learned from visiting the SABIC biotechnology lab that what I extracted is not a clean sample of DNA material, protein and cell fragments are also included in the DNA extraction. The microscope I used isn't powerful enough.
