Hello aspirant,
the exploitation of biological processes for industrial and other purposes, especially the genetic manipulation of microorganisms for the production of antibiotics, hormones, etc.
The term Biotechnology is derived from Greek word Bios, which means everything to do with life and, Technikos, which means human knowledge and skills. Biotechnology aims to produce desired health and medicinal benefits for humans by means of using advanced life sciences and living organisms like bacteria, yeast, plant cells, etc.
All the best.
