DNA extractions the surface of genetic engineering. DNA is present in the cells of living oranisms. DNA can be extracted and observed. Extracting quality DNA from scale insects, including mealybugs, can be difficult due to their small body size and waxy coating. How does detergent help to break down DNA?

After stirring for five to ten minutes, the mixture of banana and shampoo was filtered by pouring it into the coffee filter and letting the solution drain for several minutes until there was approximately five milliliters of filtrate to test.
