My hypothesis was correct, the ideal results reveal that suspect two was person who committed the crime. Sadly, the actual gel revealed very little and it was incredibly difficult to see and did not come out in the photo. The DNA I have obtained should be pure DNA, since it was filtered and separated from the rest of the solution there should be nothing else in it. In order to be certain of this an indicator could be used in order to test for other substances. The main problem with the DNA extraction procedure is simply getting all the cells I needed. Towards the end I had nearly no precipitate because I did not get all the cheek cells I needed. The only thing I could have done differently is to spend more time getting cheek cells before
