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. Then the salt and shampoo had to be dissolved into the mixture by stirring slowly by avoiding foaming. This is the DNA pieces clumping together. The remaining two bases, cytosine and thymine, are known as pyrimidines. How does detergent help to break down DNA? Extracting quality DNA from scale insects, including mealybugs, can be difficult due to their small body size and waxy coating. It was established in 1953 by James Watson and Francis Crick that the two strands of their proposed double helis are exact complements of one another, such that the rings of the ladder always consists of either A=T, or G=C base pairs. Place the coffee filter in a clear glass cup, securing the top of the filter around the lip of the cup. A water bath was prepared.
