If the steps were altered then the yield or the amount of DNA per banana could have been very small because the DNA would get trapped inside the cells or bound to lipids. Overall, the Lab: Extracting DNA from Bananas demonstrated and visualized the process of how DNA can be seen from the naked eye by removing DNA directly from bananas. Banana DNA Experiment This DNA extraction is simple and works every time but the DNA is not pure. The DNA precipitates out of the solution when the alcohol is added.

In this activity, you will extract and observe DNA from bananas. 4 0 obj Its natural shape is called a double helix and when seen under extremely high-powered microscopes, it looks kind of like a ladder twisted into a spiral shape. They produce molecules called proteins that do most of the work in the body. Lastly, when good results were obtained, there was enough DNA to spool onto a rod or a plastic loop. Because of their size, it is impossible to see a single DNA molecule with the naked eye.
