DNA extraction is a laboratory process used to isolate deoxyribonucleic acid (DNA) from cells. This procedure typically involves breaking open the cell membranes to release the DNA, followed by removing proteins and other cellular components. Common methods include using detergents and enzymes to facilitate the breakdown of cell structures. Once the DNA is isolated, it can be purified and concentrated for further analysis. This extracted DNA can be used in various applications, such as genetic testing, forensic analysis, and biotechnology research. The quality of the extracted DNA is crucial for accurate results in these fields.
