Ground breaking discoveries during 20th century in the field of physics and engineering has changed the way we live now. Similar pattern of change and advancement is being followed in 21st century driven by innovations and discoveries in biology and medicine. Biotechnology is the integral part of advanced biological research having applications in areas ranging from agriculture, medicine, diagnostics, environmental sciences, food technology, and computer sciences to basic sciences of physics, chemistry and mathematics. We are not too far when every product we consume whether medicines or food items will be of biological or natural origin and not of chemical or synthetic origin. Biotechnology involves detailed study of basic and applied biosciences including biochemistry, genetics, molecular biology, biophysics, chemistry, basic mathematics, computer sciences, fermentation technology and many other specialized subjects depending upon person’s particular interest.
