GENETIC ENGINEERING
GENETIC ENGINEERING What is genetic engineering ? It is about the tools & technologies of molecular biology for cleaving & rejoining DNA SEQUENCES from two or more different organisms. These genetically modified DNA fragments are called as RECOMBINANT DNA molecules. APPLICATIONS OF GENETIC ENGINEERING 1. These can be cloned & amplified virtually to unlimited extent. 2. Application of DNA manipulation ranges from cloning genes to cloning organisms including transgenic microbes,important crops & farm animals. 3. We can get modified food products, human gene products, medical products. 4. Hereditary diseases can be cured. 5. In forensic investigations. DNA FINGERPRINTING is a reliable technique for forensic investigation. Therefore GENETIC ENGINEERING is a kind of BIOTECHNOLOGY , alteration of genetic make up of cells by artificial means.
