ASU - Ask A Biologist, Web. OBJECTIVES * To learn basic DNA extraction processes. For example, scientists can identity genetic cell membranes if the cell wall guards the cell, DNA extraction, a detergent will cause the cell to pop open, or lyse, so that the DNA is released into solution. 6T3G]Zq`S;z*H27$21a4a@ aaSn;,8@ U (c) Or, slowly pour the alcohol down the inside of the test tube with a pasteur pipette or medicine dropper. It is incredibly small, but we can see it by extracting DNA and isolating chains of it. However, it is nice because the students get to see and hold in their hand the substance they have been studying that seems so abstract and hard to believe it even exists. Bananas and strawberries are great choices. If you took all of the DNA out of some middle-sized organism (or part of an organism, like a piece of fruit),you could see and even touch DNA.
