The technology used in genetic engineering is called recombinant DNA technology, also known as genetic modification or gene editing. Recombinant DNA technology involves altering the genetic material of an organism by inserting, deleting, or modifying its DNA sequences. This process allows scientists to introduce specific genes from one organism into the DNA of another organism, resulting in desired traits or characteristics. Recombinant DNA technology has revolutionized fields such as medicine, agriculture, and biotechnology by enabling the development of genetically modified organisms (GMOs) and the production of valuable proteins or drugs.
