Extraction Many diagnostic processes involving detection of bacteria along with viruses typically begin with extraction of DNA. In the same manner, genetic diseases are also found out through extraction. Steps in genome extraction
To initiate the extraction process, a DNA in question must be present. This is the blueprint of all living things everything alive is likely to offer a good sample for extraction. Living things like nails, small insects and even minute bacteria have DNA. This may also be found in the surface, the lining and from body tissues. Other options include: your toe or the bugs obtained from the backyard. Sources of DNA are infinite.
The extraction begins when the cell is lysed or broken down or the virus from which the genome is to be extracted. This frequently involves sonication or beating of the piece of sample. Even so, a food processor will do a lot in enabling this process. Just process the sample material for 15 seconds. This helps in the breaking down of the cells more easily than by pounding the sample. The by-product of this process is a thin piece of sample. To get the strip from the pulp, use a strainer.
The next step in the extraction of a DNA involves breaking down of the protein-based cellular walls, which is often done by addition of detergents like SDS. The soap breaks down the fatty acid linings of the cells. The sample mixture and the detergent is swirled in order to effectively mix. A small amount of enzyme is dropped into the test tube and stirred gently to make the DNA clearer and easy to view. The DNA is very fragile that hard stirring destroys it. Meat tenderizers are used to catalyze the cell. Deterioration of genome linked proteins and cellular proteins are often degraded by addition of proteases.
Precipitation is also a technique in DNA extraction. Protein's precipitation is assisted by introducing salts, for example, ammonium acetate. For samples that are vortexed using phenol-chloroform and then centrifuged, the proteins are kept in organic stage and may be properly extracted. Then it is presented from at the interface between two phases. DNA is also precipitated by mixing it with alcohol and centrifuging it. The DNA being insoluble will come out from the resulting solution containing the previously added salts.
The resulting pellet is obtained by pouring off the alcohol and dehydrating it. Later, it can be re-suspended into a shield like Tris. This often appears as a long, stringy molecule. This sums up the DNA extraction process.
