Genetic engineering involves altering an organism's DNA to achieve desired traits. This technology has been used to create genetically modified organisms (GMOs), improve crops, and develop treatments for genetic disorders. Advances in gene editing, such as CRISPR-Cas9, have made it easier to target specific genes and make precise changes.
Genetic engineering technologies hold great promise for medicine, agriculture, and environmental science. Scientists are developing genetically modified plants that can withstand drought and pests, and gene therapies are being explored to treat diseases like sickle cell anemia. While these technologies raise ethical questions, they also present opportunities to improve health and solve global challenges.
