DNA extraction and recombinant DNA technology — recombinant DNA The process of DNA extraction is necessary to isolate molecules of DNA from cells or tissues. A series of steps, including the use of protease enzymes to strip proteins from the DNA, are required for isolating pure DNA that is suitable for use in later procedures, such as cloning or sequencing.

The labeling of genetically modified (GM) food became a major issue in the European Union due to widespread public concern regarding potential risks to human health and the environment. Skeptics raised alarms about issues such as altered allergenic properties in crops, the potential for engineered genes to spread to native flora, and the possible evolution of insecticide-resistant "superbugs".12

Central to the EU's regulatory response is the precautionary principle, a policy approach that legitimizes taking preventative measures to address potential risks even when scientific uncertainty persists. This principle has been a cornerstone of EU environmental and food safety law, driving the implementation of strict labeling requirements. By the early 2000s, the EU mandated that all GM foods and animal feeds containing more than 0.9 percent GM material be clearly labeled, ensuring consumer transparency.31

These stringent regulations reflect a commitment to the ethical principle of public safety and the right of consumers to make informed choices, even as scientific panels in other regions have concluded that such foods are safe for consumption.1
