Applied genetics also plays a fundamental role in environmental public health. Biotechnology laboratories specializing in applied genetics can use DNA sequencing techniques to identify and monitor the presence of pathogens and contaminants in the environment.
For example, researchers can use applied genetics techniques to monitor the presence of microorganisms in water, air, and soil, and to identify those that pose a risk to public health. This allows preventive measures to be taken to minimize the impact of these contaminants on human and environmental health.
