Biotechnology: Revolutionizing Science, Medicine, and Agriculture | A Comprehensive Guide

Introduction

Biotechnology is the science of harnessing living organisms and biological systems to develop products and technologies that improve lives. From life-saving medicines to sustainable agriculture, biotech is transforming industries and addressing global challenges. This guide explores the basics of biotechnology, its applications, and the groundbreaking innovations shaping our future.

What Is Biotechnology?

• Definition: The use of living systems (cells, bacteria, plants, animals) to create or modify products for specific purposes.
• Key Areas:
  • Red Biotechnology: Healthcare and medicine.
  • Green Biotechnology: Agriculture and food production.
  • White Biotechnology: Industrial applications.
  • Blue Biotechnology: Marine and aquatic applications.

Applications of Biotechnology
