Study Notes

Introduction to Biotechnology

Biotechnology has multiple definitions.
One broad definition is the application of biological systems, living organisms, or their derivatives to make or modify products or processes with specific use, as stated in 1992.
Another definition is the use of biological materials to solve problems and produce useful products.

Applications of Biotechnology

A significant area of biotechnology is the production of therapeutic proteins and other medicines through genetic engineering.
