This is achievable to prepare clones of genetically manipulated plants as well as animals of agricultural significance having advantageous characteristics. This will amplify the nutritive worth of plant as well as animal food. Genetic engineering might bring about the development of plants that will fix nitrogen directly from the atmosphere, instead of fertilizers which are pricey. On the other hand, formation of nitrogen fixing bacteria that can live in the roots of crop plants will make fertilization of fields redundant.
