Describe at least two safety issue associated with DNA technology and explain how these issues are being addressed.

Summary Introduction

To explain: Two safety issues associated with DNA and how these issues are being addressed.

Concept introduction: DNA based technology is very common these days. Biotechnology is the process of manipulating the living organisms or processes to form a useful product for the mankind. It includes recombinant DNA technology, cloning, genetic engineering, DNA profiling, PCR, microarray analysis and so forth.

Explanation of Solution

Nowadays, it is easier to produce transgenic plants and animals due to advancements in recombinant DNA technology. These produce genetically modified organism (GMO) whose genetic material is manipulated through genetic engineering. This is done by inserting one or more genes (transgene) into the organism. It is used to produce transgenic plants and animals by the use of recombinant DNA technology. This alteration is done to get desirable and improved traits. There is safety issues involved with the use of recombinant DNA technology.

Safety issues:

  • The main safety issue is with respect to environment. Genetically Modified (GM) crops may have detrimental effect on biodiversity due to environment contamination...
