Biotechnology is the broad area of biology, involving living systems and organisms to develop or make products, or "any technological application that uses biological systems, living organisms, or derivatives thereof, to make or modify products or processes for specific use". Depending on the tools and applications, it often overlaps with the (related) fields of molecular biology, bio-engineering, biomedical engineering, biomanufacturing, molecular engineering, etc. For thousands of years, humankind has used biotechnology in agriculture, food production, environment and medicine.
The term is largely believed to have been coined in 1919 by Hungarian engineer Karl Ereky. In the late 20th and early 21st centuries, biotechnology has expanded to include new and diverse sciences such as genomics, recombinant gene techniques, applied immunology, and development of pharmaceutical therapies and diagnostic tests.
Biotechnology plays a great role in every sector of scientific research and making it inevitable that in the future the number of jobs offers will be very high. Hence it is also a very popular course. It has a broad spectrum of applications in various fields such as agriculture, pharmaceuticals, chemicals, environmental sciences, animal sciences, human sciences, medical sciences, etc.
