Some examples of biotechnology include human gene therapy, genetically modifying plants and changing the genes of bacteria. Biotechnology helps improve crops so they produce more, healthier produce. It also helps fight human diseases.
Biotechnology is generally involved in changing the genes of a an organism to get the desired result. It affects the most people through genetically modified crops. Genetic modification of crops started thousands of years ago through selective breeding for preferred traits, but with the advances in technology in the modern day, scientists are able to directly manipulate genes. These plants produce higher quality food at a higher rate, and are often resistant to pests and diseases, which helps feed larger amounts of people for a lower price on less land.
Biotechnology more directly helps humans with gene therapy and the modification of bacteria to produce insulin for patients with diabetes. Gene therapy can help reduce or remove the effects of a disease, such as cancer or AIDS, but is still mostly in research and development. This type of therapy is still promising and has had good results in testing phases. Modified bacteria cells that produce insulin as they age helps treat and control the effects of diabetes in humans over time.
