Genetic Engineering Concepts and Applications

Genetic engineering involves manipulating an organism's genetic material using biotechnology. It has applications in agriculture, medicine, and industry, such as developing pest-resistant crops, producing new drugs, and creating useful proteins. Techniques include recombinant DNA technology, gene editing, and gene synthesis. While offering many benefits, genetic engineering raises safety and ethical concerns, leading to strict regulations. Various types of genetic engineering, like gene therapy and synthetic biology, have unique applications and challenges.
