DNA extraction paragraph

In simple terms, DNA extraction is the process of removing DNA, or deoxyribonucleic acid, from viruses or cells in which it normally resides.  DNA extraction is often used to find viruses and bacteria in the environment as well as genetic disorders or diseases such as, FISH and T-RFLP. Basically, the way to extract cells is to break open the cell or virus containing the DNA needed. Then a sort of detergent is added and the cellular proteins may be degraded so the addition of salt is important and will allow it to be drawn carefully.  You then wash the resulted DNA and are able to put it back in the body it belongs to. Over all, DNA extraction is a very important part of curing diseases and viruses that could exist in your cells.
