Introduction

Biotechnology is one of the most important fields in modern science. It combines biology with technology to develop products, processes, and solutions that can benefit people, agriculture, industry, healthcare, and the environment. What Is Biotechnology

The word biotechnology comes from two ideas: biology, which is the study of living organisms, and technology, which involves using scientific knowledge to solve practical problems. In simple terms, biotechnology means using living organisms, cells, biological molecules, or biological processes to create useful products and technologies. What Is Biotechnology

Biotechnology is not entirely new. Humans have used biological processes for thousands of years to make foods such as bread, yogurt, cheese, and fermented beverages. Modern biotechnology, however, uses advanced scientific techniques involving genetics, molecular biology, cell biology, bioinformatics, and engineering. What Is Biotechnology

Today, biotechnology is used to develop medicines, improve crops, manufacture industrial products, study diseases, produce biological materials, and investigate environmental problems.
