Biotechnology covers many disciplines such as genetic engineering, biochemistry, molecular biology, medicine, agriculture etc. In medicine, biotechnology has been applied in the development of medicines and therapies, etc. In agriculture, biotechnology is applied in the development of genetically modified plants, biofuels, biological treatment as well as to solve other agriculture-related issues. In the industries, through genetic engineering, simple cells and proteins has been engineered to produce useful chemicals such as drugs, hormones, etc.
Since George's studies involves cell culturing and genetics of plants in order to develop technology that will improve plant production and solve other agriculture-related problems, he is studying Biotechnology.
