Genetic Engineering Is An Allergic Reaction Between Cows And Carbohydrates

Genetic engineering is the process of being able to manually add new DNA to an organism. This is to try and add one or more new traits to an organism, which does not have these certain traits. An example of this being done is how bacteria have been genetically engineered to produce human insulin. Insulin is a hormone, which is produced by the pancreas that allows the body to use sugar from carbohydrates in food that is eaten for energy or to store glucose for future use. Basically insulin helps your body keep your blood sugar levels from becoming too high (hyperglycemia) or too low (hypoglycemia). But for people with type 1 or 2 diabetes it can be a challenge to produce insulin, as their beta cells in the pancreas are destroyed/damaged or do not respond well or are resistant to insulin. Therefore these people need to gain their insulin from an external source. For many years it was gained from the pancreas of a cow or a pig. However this was very expensive and difficult, also the insulin could cause allergic reactions. This is where genetic engineering came in. Once the structure of human insulin was found in 1955 cow and pig insulin could be chemically modified to be the same as human insulin. Genetically engineered microbes now make it. They produce human insulin in a pure form, which is less likely to cause allergic reactions.

It is used to treat diabetes but is limited in supply and does not suit all people. The non-natural way to create insulin is to use genetically modified bacteria. The gene for creating insulin is taken out from human DNA and placed into the DNA of a bacterium. The bacterium is refined and after a while millions of bacteria are producing human
