Genetic Engineering Wiki

http://geneticeng.wikispaces.com/

Through my wiki, I will be presenting to the class how genetic engineering works through plants, animals, and human beings. I will explain the process on the engineering, and the pros and cons. The research I have found is very accurate because many sites contain the same information. In years to come, genetic engineering can potentially harm our society and ourselves.

On my wiki I will contain six sub-pages. Genetic engineering on plants, humans, and animals. Please take your time to click on the link and further view my wiki.

End of Journey

Sadly to say, this will be the last of the blog postings about genetic engineering. This project has helped me learn more about humans, plants, and animals. It created a visual image in my mind on how people may have there body look like if they didn't like their original features. Humans have many varieties of ways to manipulate their body. Whether its becoming stronger, more athletic, different eye color, or hair color.

Genetic engineering also paved the way to better understand the types of food I eat. Nevertheless, there are many pros and cons to genetic engineering. It benefits our society in many ways, but yet destroys it slowly. Thank you all for following up on this interesting topic.

Pros and Cons of Human Genetic Engineering

Many people in the world have a fear of dieing. Many people would love to live longer and some people just want to live their normal life. If you had the opportunity to be remade and live longer, would you take that opportunity? With technology advancing, it is possible to increase the live span for humans to 100-150 years. Many people also have the dream to remain young forever. Scientists are advancing on this dream and are trying to make it possible to slow down certain cellular metabolisms.

Scientists supposably say that with genetic enginnering, the body will be free of diseases. I don't think that is true because everyday something new is discovered. New diseases form and somehow will find a way around the blockage to attack the human body. Nevertheless, it is also good to be sick sometimes. The immune system learns of the disease or sickness and can produce anti-bodies to help from getting this disease or sickness again. It only makes the body stronger.

Why Genetic Engineering is a Threat to the Environment...

Considering over a million of years plants have been interbred through the wind and pollination, scientists are beginning to stop that natural aspect of breeding. For example " The new Monsanto soybeans, called Roundup-Ready Soybeans (RRS), now have non-soybean genes in their cell nucleus. Thus in a tiny instant of time Monsanto crossed a genetic boundary that could not be crossed naturally." [Campbell] Now, the only way in the U.S. to buy unmodified foods is buying something marked "organic". The Food and Drug Administration tried to change that by adding genetically modified goods in organic packaging, but the public stopped that. Do you feel safe eating genetically modified food?

Will Cloning Animals be Beneficial?

The first ever clone of an animal was done on a sheep named Dolly. It took scientists 277 attempts to successfully clone the sheep. However, there can be some flaws in cloning in animal. Taking DNA from the embryos can cause many mutations in the cloned animal. Many scientists are still trying to figure out if cloned animals can reproduce. Considering that animals can now be cloned, would you want animals to be cloned too? Nevertheless, we have these big athletes emerging in every sport. What happens if someone like Lebron James was cloned? Sports will be no fun to watch or play. 


I think that cloning ruins society's individuality. Why would people want to see a multiple of the same things. Things would get boring to look at. Soon enough, the whole world will be acting the same and performing the same tasks.

Can Genetic Diseases Be Stopped?

According to research at least 1,500 genetically passed on diseases have been discovered. Throughout the years, diseases are enhancing and becoming a very extreme medical problem amongst the population. Nevertheless, because of these diseases, scientists have been better able to understand the structure of DNA and the structure of the human body.

Genetic diseases are usually treated by dietry therapy, drug therapy, or gene product replacement therapy.  Diets low in lactose are used to treat individuals with galactosemia. Drug therapy is used to reduce or block the accumulation of compound C.  Good enough, it is possible to detect a genetic disease by diagnosis of the utero.

Modified Foods

Genetically modified foods consist of combining genes from different organisms. Food is most likely altered because of insects and farmers want to have "insect resistance" on their plants. Would genetically engineered food be good for humans? Would the food cause human allergies? Many questions are still waiting to be answered. Many cancers could evolve from these genetically engineered foods. Even animals are becoming engineered to reproduce faster and produce meat differently.

Most importantly, the ecosystem. Genetically engineering animals and foods changes the outcome of the environment around them. Genes can cause an uncontrollable side effect that can wipe them of the face of the earth. Some forms of pollution can be contained but for gene pollution it cannot be contained. Cross-pollination can carry genetically changed organisms to other places and can cause harmful species.

GM Products: Benefits and Controversies

Benefits

• Crops

  • Improved resistance to disease, pests, and herbicides
  • New products and growing techniques
• Animals
  • Increased resistance, productivity, hardiness, and feed efficiency
  • Better yields of meat, eggs, and milk
  • Improved animal health and diagnostic methods
• Environment
  • "Friendly" bioherbicides and bioinsecticides
  • Conservation of soil, water, and energy
  • Bioprocessing for forestry products
  • Better natural waste management
  • More efficient processing
• Society

Controversies

• Safety
  • Potential human health impacts, including allergens, transfer of antibiotic resistance markers, unknown effects
  • Potential environmental impacts, including: unintended transfer of transgenes through cross-pollination, unknown effects on other organisms (e.g., soil microbes), and loss of flora and fauna biodiversity
• Access and Intellectual Property
  • Domination of world food production by a few companies
  • Increasing dependence on industrialized nations by developing countries
  • Biopiracy, or foreign exploitation of natural resources
• Ethics
  • Violation of natural organisms' intrinsic values

  • Mixing GM crops with non-GM products confounds labeling attempts
• Society
  • New advances may be skewed to interests of rich countries
