This mixture was strained into the beaker where the detergent was mixed in and the mixture was allowed to sit before being poured into the five test tubes, with (roughly) equal amounts of the mixture in each tube. Four to six drops of contact lens cleaning solution was added to each test tube and gently stirred with a cotton swab. Alcohol was then slowly poured down the side of the test tube, until an amount roughly equal to that of the underlying mixture rested at the top portion of the tube.
Results:
As expected, DNA precipitated in the border region where the water mixture met the alcohol in each test tube. This DNA material appeared as white clumps of strands in the test tubes, and was removed using cotton sticks. Substantial amounts of the DNA formed in each of the test tubes.
Discussion:
The amount of DNA that precipitated in each test tube shows this to be a very efficient and a highly viable method for extracting DNA from almost any source, including the leaf of a hardy yet common weed. Other research has even...
From a variety of forensic uses to promises of expanded anthropological knowledge, the technique described and affirmed by this experiment can be useful in a number of investigations and a myriad of individual uses.
