Throughout the entire experiment there were many possible ways that the ending result of the appearance of the DNA could have differed. For more info, see, https://askabiologist.asu.edu/activities/banana-dna, Public Service and The ability to extract DNA is of primary importance to studying the genetic causes of disease and for the development of diagnostics and drugs. 3) Then alcohol added to the solution causes the DNA to precipitate out. We are going to use fruits because they are soft and easy to pulverize. In this activity each material plays a specific role in helping to extract the DNA from the cells. A water bath was prepared. Do this for 30 to 45 seconds. For more info, see, Modern Language Association, 7th Ed. The positively charged sodium ions in the salt help protect the negatively charged phosphate groups that run along the backbone of the DNA.
