Biotechnology is a branch of science that uses living organisms, cells, and biological processes to develop useful products. It plays a vital role in healthcare, pharmaceuticals, agriculture, food technology, and environmental protection. Biotechnology supports drug discovery, vaccine development, genetic engineering, and industrial applications, contributing to improved quality of life and sustainable development across various scientific and medical fields.
Biotechnology Overview
Biotechnology is a branch of science that uses living organisms, cells, or biological systems to develop useful products and processes. It combines principles of biology, chemistry, and technology to improve human life. Biotechnology is widely applied in healthcare, agriculture, food production, and environmental management. In medicine and pharmacy, it plays an important role in the development of vaccines, antibiotics, enzymes, and modern biopharmaceuticals.
Contribution of biotechnology in various fields
Biotechnology is broadly classified into different types based on its applications in various sectors.
Medical Biotechnology
It is a branch of medicine that uses living cells and cell materials to research and then produce pharmaceutical and diagnosing products
Industrial Biotechnology
Industrial biotechnology refers to the use of microorganism or biological substances such as enzymes to performs industrial or manufacturing process.
Animal Biotechnology
It is a branch of biotechnology in which molecular biology techniques are used to genetically engineer animals in order to improve their suitability for pharmaceutical, agricultural or industrial applications.
Environmental Biotechnology
Biocontrol and management of plant-borne disease and insect pests by employing amoeba, bacteria, fungi, viruses etc.
