DNA recombinant

• Biotechnology involves using live organisms or enzymes from organisms to produce products and processes useful to humans
• Biotechnology includes processes like in vitro fertilisation, gene synthesis, DNA vaccine development, and gene correction
• Two core techniques of modern biotechnology are genetic engineering and maintenance of sterile ambience in chemical engineering processes
• Genetic engineering techniques include creation of recombinant DNA, gene cloning, and gene transfer
• Recombinant DNA is replicating DNA created in vitro and transferred into host organisms
• Herbert Boyer and Stanley N. Cohen developed recombinant DNA technology, allowing genetically engineered DNA molecules to be cloned in foreign cells
• Recombinant DNA technology started in the early 1970s, enabling the transfer of genes between bacteria and the production of genetically modified organisms
• Genetically modified crops can resist herbicides, insects, and diseases, increasing yield and reducing the need for chemical sprays
• GMOs are organisms with genetically altered DNA, modified to meet human demands like food supply
• Advantages of GMOs include increased food production, reduced pesticide use, and potential for nutrient enhancement
• Disadvantages of GMOs include unknown long-term effects, potential creation of new allergens, and concerns about environmental and health impacts
• Organic farming, which avoids chemical pesticides and fertilizers, has gained popularity due to concerns about GMOs
• Applications of DNA recombinant technology in crop improvement include distant hybridization and development of herbicide-resistant and disease-resistant crops
• rDNA is the most important tool used by genetic engineers, without which genetic engineering would not be possible
• With rDNA, scientists can produce proteins in the laboratory, such as vaccines, human insulin, and human growth hormones
• Before genetic engineering, insulin used to treat diabetes was isolated from pigs and cows
• Biotechnology has had a positive impact on agriculture, enabling the production of genetically modified crops with higher quality, yield, and resistance to pests
• Transgenic crops may lead to market instability, reduced export income, fewer product varieties, and unemployment due to overproduction
• Genetically modified organisms may escape into the wild, upsetting the balance of ecosystems and causing a decrease in biodiversity
