I hope to test this at some point to confirm some of these comments, but as my source for many of these protocols, I know he is rarely, if ever wrong. This is because the base pairs in DNA absorb UV light, therefore amount of bp is directly proportional to DNA concentration. DNA extraction is the process of isolating DNA from the cells of an organism isolated from a sample, typically a biological sample such as blood, saliva, or tissue .
