A revolution by recombinant DNA technology to improve the quality of life

The emergence of recombinant DNA (rDNA) technology occurred through the appropriate use of known procedures and tools in novel ways that resulted in broad applications for modifying and analyzing gene structure and organization of complex genomes. In the past centuries, the production of organisms having desirable traits was a mere imagination. Nowadays, rDNA technology has revolutionized the field of science, having vast and multidisciplinary applications, and products that were impossible to produce by conventional or traditional methods. With the aid of rDNA technology, impossible things could be achieved. rDNA technology has vital applications like plant and animal production, health improvement, increment in food resources, treatment of serious diseases, protein development, improved environmental conditions, etc. This technology plays a crucial role not only in the betterment of health conditions by the development of pharmaceuticals or new vaccines but also in improving the treatment strategies by developing monitoring devices, novel therapeutic approaches, and new diagnostic kits. This review mainly emphasizes the possible roles of rDNA technology for human welfare.
