Genetic modification is a scientific process that involves altering the DNA of an organism. This can be done to enhance certain traits, such as resistance to pests in crops or improved nutritional content in foods. By using techniques like CRISPR or gene cloning, scientists can add, remove, or change specific genes to achieve desired characteristics. This technology is widely used in agriculture, where genetically modified organisms (GMOs) can lead to higher yields and reduced reliance on chemical pesticides. However, genetic modification also raises discussions about safety, ethics, and environmental impact, making it a topic of ongoing research and debate.
