Genetic Engineering for Human Welfare

In Techniques of Genetic Engineering, construction of recombinant DNA and its cloning into bacteria and plant/animal cells are described. Following these techniques thousands of DNA fragments of pro-and eukaryotes (plant and animals) have been cloned during fee last two decades. According to the utility the cloned DNAs can be used in basic research or commercial production of useful products. Basic research includes DNA probe, expression of cloned genes, colony/ plaque hybridization, genome mapping and many more related to genetic engineering.

Moreover, cloned genes are utilized commercially in, medicals, agriculture and industry, and the production of valuable products. An outline of arcja applications of genetic engineering techniques is given in Fig. 5.1. In this connection some of the cloned genes and application of genetic engineering techniques are described here.
