Genetic engineering has advanced the understanding of many theoretical and practical aspects of gene function and organization. Through recombinant DNA techniques, bacteria have been created that are capable of synthesizing human insulin, human growth hormone, alpha interferon, a hepatitis B vaccine, and other medically useful substances.
Genetic engineering, although a recent concept, has roots in ancient human practices like selective breeding of animals and plants. Today, recombinant DNA technology enables precise gene manipulation, creating genetically modified organisms (GMOs) with enhanced traits.
May 2, 2024 · Definition. Genetic engineering (also called genetic modification) is a process that uses laboratory-based technologies to alter the DNA makeup of an organism. This may involve changing a single base pair (A-T or C-G), deleting a region of DNA or adding a new segment of DNA.
Genetic engineering is the directed addition of foreign DNA (genes) into an organism. Five basic steps in crop genetic engineering: DNA extraction – DNA is extracted from an organism known to have the desired trait. Gene cloning – The gene of interest is located and copied.
