Strawberries Dna Extraction

If strawberries are living things, then DNA will be able to be extracted using the DNA extraction buffer. The hypothesis was supported because once the DNA was seen when the ethanol was added, the DNA precipitated. The DNA looked and felt like cotton candy that turned into slimy mucus. Before the inoculating loop was added, individual strands of DNA that looked like strings were seen. There is no correlation because there is no graph in this lab. The results look this way because the DNA made a reaction to the ethanol, and the strawberry is a living organism. This relates to the cell theory because all living things are made from cells, which have DNA, organelles, and the membranes that need to be broken down. The membranes were broken down by adding extraction buffer to the mashed up

The membrane and nucleus had to be broken down since the DNA is found inside, which is found inside the membrane. A possible source of error could have been if a chunk of a strawberry got into the test tube with the filtrated strawberry juice and DNA extraction buffer. DNA is soluble, but not in ethanol. This is why when the ethanol was added, the DNA was then visible. This could have affected the data because there might have been organelles and other parts of the strawberry besides the DNA that wasn’t supposed to be there in the filtrated strawberry juices and extraction buffer. Another source of error could have been if the bag with the mashed strawberry in it had a hole in it. This could have affected the results because parts of the DNA could be lost, and the data would then be different. If strawberries are living things, then DNA will be able to be extracted using the DNA
