In this activity each material plays a specific role in helping to extract the DNA from the cells. The information in DNA tells our bodies how to develop, grow, and work. 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. In this study, we evaluate eight commonly used DNA extraction methods to determine their efficacy in PCR analysis across life stages and preservation . You may see some bubbles and cloudy material moving around in the alcohol. And because DNA doesn't dissolve in alcohol, this substance helps DNA to cluster into a separate layer. 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.
