banana dna extraction lab report conclusion

Although nowadays very few errors are made due to scientists using biotechnology equipment that allows them to look at DNA to see exactly how organisms are different, and find out how they work. My hypothesis was correct for strawberries producing the most DNA followed by kiwis and than bananas last. Aim: To extract DNA from a banana using simple household items Hypothesis: DNA is found in the cells of every living organism.
