What are the 4 main applications of biotechnology?

Introduction

Welcome to the world of biotechnology, a field that is constantly pushing the boundaries of science and technology. From medicine to agriculture, biotechnology has made its way into various industries, offering endless possibilities for advancements and innovations.

To understand biotechnology, let's break down the term itself. “Bio” refers to living organisms, while “technology” refers to the use of scientific knowledge for practical purposes. Biotechnology, therefore, combines these two elements by using technology to manipulate biological organisms and processes.

The field of biotechnology has been around for centuries, with early practices such as fermentation and selective breeding dating back to ancient times. However, it was not until the 1970s that we saw significant advancements in biotechnology with the emergence of genetic engineering techniques.

What is Biotechnology?

Let's define biotechnology. It is a term that combines biology and technology using technology to study and manipulate biological processes. This involves the use of living organisms or their components to create useful products or perform beneficial tasks.

Now that we have a general understanding of what biotechnology is, let's take a closer look at its main applications. There are four main areas where biotechnological advancements have had a significant impact: healthcare, agriculture, energy, and environmental conservation.
