What are “Bt crops”? What potential risks are associated with this technology?

Summary Introduction

To define: The term “Bt crops”.

Introduction: In classical breeding techniques, transfer of hundreds to thousands of genes takes place to develop transgenic crops. These days, however, methods of biotechnology such as recombinant DNA techniques are used to develop transgenic plants at a faster and more precise rate. Genetically modified plants are the plants which are produced by the methods of recombinant DNA technology.

Explanation of Solution

The transgenic crops which are resistant to insect pests are known as Bt crops. Bacteria named Bacillus thuringiensis produce a crystal protein which is toxic for various insects which are pathogenic for the crop plants. The gene encoding this protein is isolated from the bacteria and inserted into the plant genome using recombinant DNA technology to produce Bt crops...

Summary Introduction

To determine: The potential risks associated with the technology used to develop Bt crops.
