Introduction
Genetic engineering is one of the most useful process for producing medicine, plants and animals with faster growth rate and higher nutritional value. However, the is also one of the most controversial subjects in the world, yet most of us are eating it every day. Products such as canola oil, biscuits and chocolates, soy mile, or tofu are example of genetically modified food. Canola oil is an important product used in cooking and therefore some of us consume it daily. Some concerns around the use of genetically modified foods include, companies being able to take control of the production of certain foods and also some plants can produce unexpected traits which could affect the nutritional value of the crops or cattle in some

The gene for making insulin is cut from human DNA using restriction enzymes
2. It is then inserted into a plasmid using ligase enzymes.
3. The plasmid is then placed into bacterial vector in the animal
4. The transgenic bacteria reproduce in animal, resulting in millions of identical bacteria that produce human insulin

Advantages
One major advantage of genetic engineering is that enables the production of insulin which can be used in the treatment of diabetes. This is important because the number of people suffering from diabetes is increasing. For insistence in Australia there have been approximately 1 million Australians diagnoses of diabetes. Where 130,000 of this is suffering from type 1 diabetes. Australia has the 7th highest prevalence and 6th highest incidence of type 1 diabetes in children aged 0-14years. With the aid of genetic engineering the requirement for insulin can be met. This is because genetic engineering can be used to produce insulin, via implanting the human gene for insulin in a plasmid and then injecting it another organism. This allows that organism to produce insulin, which can be used to treat diabetes. Therefore, as the number of diagnoses is increasing every year the requirements for insulin is growing, so it is necessary that genetic engineering be used to help create a sustainable source of

Genetic engineering can be used to improve crops, by incorporating genes from other plants which can introduce new traits which can help to improve suit their environment, growth and breed at a faster rate, and also to add nutritional value. In terms of disease, the resistant genes can be isolated and transferred to high yielding plants to produce pathogen free plants. Through gene sequencing, it is possible to locate gene and after identification, the gene is isolated and transferred to the host. One instance of this is that scientists have been able to use the Agrobacterium gene which can help the tobacco plants to develop an increased resistance to Tobacco Mosaic Virus (TMV). (see
