Transgenic organisms are living beings that have had genes from other species inserted into their DNA. This process is done using biotechnology techniques, allowing scientists to create organisms with specific traits, such as resistance to pests or improved nutritional content. Common examples include genetically modified crops like Bt corn, which produces a natural insecticide. These organisms can be used in various fields, including agriculture, medicine, and research. For instance, transgenic mice are often used in laboratories to study diseases and test new treatments. The development of transgenic organisms raises important ethical and environmental questions that are actively discussed in society.
