My Personal Evaluation
Genetic engineering with recombinant DNA to make transgenic organisms has been a topic of intrigue and controversy for many years now. As our understanding of recombinant DNA has grown the amount of things we have been able to do with this technology is short of miraculous. From us intervening and using selective breeding to get the attributes we wanted, to introducing genes from other species using plasmids to inject the genes into cells to now where we can create brand new genes from scratch the advances have been remarkable.
Transgenic organisms or more commonly known as genetically modified organisms have become common place in today’s society. They are used predominantly in agriculture. Canada is the third largest producer of transgenic crops in the world. We produce around seven percent of the worlds genetically modified food supply. Genetically modified crops can be made heat, cold, and pest resistant. They can also be modified to thrive in arid environments. Recombinant technology is also used to make organisms reach maturity faster and crops produce higher yields. This is a step in helping fight hunger across the world.
The way recombinant DNA technology works is by inserting the DNA from the gene you want to add into a plasmid which is a circular shaped group of DNA in a bacterium. The bacteria then reproduces the gene and replicates and we can harvest it. Of it is put into the cell of an organism and similar steps happen. By introducing the DNA in this manner the cells or bacteria will produce on their own .
The down sides of Genetic modification are many. When a genetically modified organisms are put into the environment they cannot be controlled and can potentially cross breed or out compete the local or naturally occurring species in the area. They may also cause unknown health effects to people and animals. We know so little it may turn out that genetically modified tomatoes are causing peoples toes to turn into short stubby fingers. :P In all honesty though the risks are many but unknown and there is only so much we can do. I believe that we should continue the study and use of GMO’s and recombinant DNA technology but make sure there are fair regulations
such as making it mandatory for companies to label products with GMO’s in them. They can also make it mandatory to have certain standards necessary when it comes to farms that use GMO crops to prevent from spreading accidentally. Due to the fact that we don’t know any of the actual risks it will be difficult to mitigate but by observing everything carefully and keeping a hand in what is going on we can control things and react as quickly as possible if necessary.
