Genetic Engineering Lesson
Genetic engineering is very similar to selective breeding because they are techniques used to produce an organism with desired traits. Genetic engineering is a process used to transfer genes from one organism to another organism to improve crops or cure diseases. Diabetes is a disease in which the body is unable to produce enough or any insulin. The human body's ability to convert glucose into energy is controlled by the hormone, insulin. In the 1980s, the first genetically engineered drug, human insulin, was produced. Scientists inserted the genes for human insulin into bacteria. The bacterial cells were able to produce insulin for humans. Many people with diabetes inject themselves with genetically modified insulin. One example of how plants have been genetically modified is the new type of rice seed developed for farmers in China. Genes were inserted into the rice seeds to make them more flood resistant. The new rice could survive submerged in water for approximately 17 days. This was a major advantage for rice farmers who not only use the rice for economic profit but also for food to feed their families. Genetic engineered crops such as cotton, corn, and soybeans are being grown worldwide.
Should We Grow GM Crops?
Humans want better crops and are willing to guide reproduction in animals and plants to yield ideal livestock and crops. Doing so means being able to feed more people but should we tinker with nature?
