Genetic Engineering By Faith Coggin
What is Genetic Engineering? Genetic engineering, also known as genetic modification, is the altering on DNA in an organism’s genome. A genome is a set of genetic instructions. It contains all of the info needed to be construct an organism and allow it to grow and flourish. It can also mean extracting another organism’s genome and combining it with the DNA of another organism. This enhances certain characteristics of an organism or adds new ones.
How does Genetic Modification/Engineering work? A small piece of DNA may be removed, as in a plasmid of bacteria (a small circle of genetic matter). A small section of the plasmid is then cut out by restriction enzymes (also called “molecular scissors”). The gene from another organism, such as human insulin, is inserted into the area that had been cut of the bacteria and is then introduced into a new bacteria cell. The cell divides at a fast rate, producing insulin
A fermentation vessel may be used to facilitate bacteria growth. The more cell divisions, the more insulin that is produced. In order to purify the insulin, it is filtered through a filtration system that will release the insulin. The insulin is then packaged and distributed.

What are the pros of Genetic Engineering? Pros of genetic engineering include, more nutritious food, longer shelf life, pest resistant crops, a faster growth rate and a higher crop yield. All are very important for sustaining a growing population of a society. Another pro that was talked about earlier is the development of new medicines, as well as things that may not be produced naturally in the body, such as insulin, to help people with diseases like diabetes.
Cons of Genetic Engineering also has some complications that come along with it, such as decreasing nutritional value of certain foods, introducing new harmful pathogens, increase in genetic defects and decreasing in genetic diversity. Designer babies are an example of a controversial issue in the science community. Some believe it will lead to growth and prosperity, but others believe it will lead to inequality and believe it may be taken too far
