Biotechnology is one of the fastest growing sectors of the global economy. Biotechnology is applied mainly in the manipulation and modification of molecules as well as living organisms, to develop better products, accelerate industrial processes, produce safer food and ameliorate the quality of our environment. Biotechnology encompasses an exciting range of scientific fields including biological science, biochemistry, agricultural, pharmaceutical, medical and environmental sciences. Computer Science and information technology have added another great dimension in biotechnology applications, the bioinformatics. The history of biotechnology goes back to thousands of years, where microbes were used for the fermentation process in bread making. However, recently new tools of biotechnology enabled scientists to modify and manipulate living organisms by altering their DNA with high precision.
