Introduction Bacterial transformation is the permanent alteration of a bacterial cell genotype as a result of its uptake and incorporation of foreign DNA fragments from external medium (Anthony et al‚ 2008). In addition to chromosome‚ bacterial cells often contain extrachromosomal DNA called plasmids which are capable of autonomic replication and antibiotic resistance (Dale & Simon‚ 2010). Plasmids can transport foreign DNA into host or other bacterial cells hence they are known as vectors.

barriers which stop different species of organisms from breeding with each other. Genetic modification is very different to these traditional plant breeding techniques. Genetic modification is the insertion of DNA from one organism to another‚ usually by molecular technologies. Genetically Modified Foods (GMF) are animals or plants that have had genetic modification. This changes the characteristics of the organism‚ or the way it grows and develops.

science behind genetically modified food has been around since the nineteen-seventies with a respectable safety record to support its production. The advances have helped saved millions of lives in places like India‚ Bangladesh‚ and Southeast Asia with the production of Golden Rice. There are no known risks of genetically modified food however there is speculation that is can cause autism and allergic reactions because of the genes added or altered. The most common genetically modified foods are corn

DEBATE REGARDING GENETICALLY MODIFIED CROPS INTRODUCTION:- For thousands of years‚ human beings have modified nature’s organisms for usage in agriculture. New technology has furthered this trend: recombinant DNA technology allows biotechnology firms to insert DNAs into plant genomes‚ thereby creating plants that express the desired traits. Use of such genetically modified organisms (GMOs) has prompted controversy‚ especially for its role in ensuring food security. As such‚ the use of

Introduction Plasmids are circular‚ double stranded extrachromosomal DNA molecules that are found in bacteria which can self-replicate. They are naturally occurring DNA molecules advantageous to the host bacterium by carrying genes which specify metabolic capacities. (Garrett et al.‚ 2010) Besides‚ plasmids exist in a wide variety of sizes from a few thousands to hundreds of thousands of base pairs. Many plasmids have been engineered to serve as plasmids cloning vectors to carry genes. (Synder et

Genetically modified (GM) foods‚ a fairly recent development that came about from research in genetic engineering‚ pose a potential threat to human and environmental health. The basis of genetically modifying foods is the transferal of desirable genetic traits of plants to an agricultural crop. Genetic modification creates crops that are resistant to herbicides or can repel insects. Genetic modification also makes growing crops easier and allows for higher production rates.

Genetically Altered Animals In 1980‚ after years of extensive research‚ Rudolf Jaenisch created the first genetically modified animal using a mouse. Today‚ the number of genetically modified animals has increased dramatically‚ especially in agriculture. Currently‚ farm animals such as sheep‚ cattle‚ chickens‚ and pigs have been genetically modified. More and more animals are being experimented on everyday so that humans can benefit from the advanced products they produce such as better food and

Around the beginning of 1975‚ Monsanto shifted its focus to biotechnology and introduced genetically modified plant cells. It switched its emphasis from chemicals to food. Now‚ the Monsanto Company is the world’s largest seed company. Because the company is so big‚ there are multiple problems to be dealt with. Environmental concerns would be one of the major issues. Since the GMO is something new‚ no one can assure future consequences. Another thing would be the organizational ethical issue. “Bribery

The article called Genetically Modified Foods‚ has a style that is use to grab an audience emotion while still putting some facts. Right away in the first paragraph you will find ethos. Per Pinstrup-Anderson plays a key role in the article‚ he is the H.E. Babcock Professor of Food‚ Nutrition and Public Policy at Cornell University. Giving Per Pinstrup-Anderson a creditability‚ and having the audience attention. This is the only time in the article when ethos is being used to help their argument

Ever since the 1970s‚ genetically modified food have been rising in North America and even a couple of European countries. In the 1980 ’s Biotechnology companies began field-testing GMO (genetically modified organism) crops for large-scale agricultural use. By 1996‚ GMO grains were mixed with non-GMO grains and sent to food processing plants all over America. One of the first organisms to be genetically modified and sold in store shelves is the tomato because scientist found out a way to make it
