Retroviruses go a stage further by having their genetic material copied into the genome of the host cell. A number of viruses have been used for human gene therapy, including retrovirusesadenovirusesherpes simplexvacciniaand adeno-associated virus.
Most Americans Accept Genetic Engineering of Animals That Benefits Human Health, but Many Oppose Other Uses Public concerns about animal biotechnology focus on risks to animals, humans and the ecosystem By Cary Funk and Meg Hefferon As Americans consider the possible uses of genetic engineering in animals, their reactions are neither uniformly accepting nor resistant; instead, public reactions vary depending on the mechanism and intended purpose of the technology, particularly the extent to which it would bring health benefits to humans.
Presented with five different scenarios of animal genetic engineering that are currently available, in development or considered possible in the future, Americans provide majority support only for the two that have clear potential to pre-empt or ameliorate human illness.
And one application that is already commercially available is largely met with resistance: These are some of the findings from a new Pew Research Center survey, conducted April May 6 among a nationally representative sample of 2, U.
Men are more accepting of these uses of technology than women, those with high science knowledge are more accepting than those with medium or low science knowledge and those low in religious commitment are more accepting than those with medium or high levels of religious commitment.

However, evolved resistance to current GE characteristics in crops is a major agricultural problem.|
Emerging developments in animal biotechnology raise new social, ethical and policy issues for society, including the potential impact on animal welfare. There are large differences between these groups when it comes to using animal biotechnology for humans needing an organ or tissue transplant and the idea of using such technology to produce more nutritious meat.
A common refrain in these responses raised the possibility of unknown risks for animals, humans or the ecosystem. Some saw these technologies as humankind inappropriately interfering with the natural world or raised general concerns about unknown risks. One respondent put it this way: By preventing their reproduction, we risk disrupting the entire ecosystem.
Who knows what side effects this could cause? Even human-to-human organ transplants often reject, so I can only imagine the bad side effects that an animal-to-human transplant would cause.
Keep things simple and the way nature intended. Those who think this is taking technology too far raised a number of different concerns.
One example of these concerns: There is no need to try to increase nutrition. Rather we should be decreasing human reliance on meat as a foodstuff. Consider the problems man has created by reintroducing species that have become extinct [in] a given area, i.
Extinction is part of evolution of the universe. We have no right to bring animals back and play God. A sampling of these concerns: Is there a benefit to humanity other than having a rare zoo specimen? Would the extinct species cease to become extinct through natural reproduction — if not that, the whole effort is without merit.
Would it provide a better way of life for humans? At this point it would just [be] playing God to entertain rather [than] help us.
Technology should be used to help people, animals and the environment, not put on a glow show. If you only do something because you can is not a good reason.
If any genetic engineering is allowed it will get out of hand.Genetic engineering became possible only when scientists had discovered exactly what is a gene. Prior to the s, the term gene was used to stand for a unit by which some genetic characteristic was transmitted from one generation to the next.
Biologists talked about a "gene" for hair color. Elon Musk doesn’t want to get into genetic engineering because he doesn’t know how to avoid 'the Hitler problem'. The nation turns to the National Academies of Sciences, Engineering, and Medicine for independent, objective advice on issues that affect people's lives worldwide.
Distinction Between Genetic Engineering and Conventional Plant Breeding Becoming Less Clear, Says New Report on GE Crops WASHINGTON – An extensive study by the National Academies of Sciences, Engineering, and Medicine has found that new technologies in genetic engineering and conventional breeding are blurring the once clear distinctions between these two crop-improvement approaches.
Genetic engineering is the direct manipulation of an organism's genome using certain biotechnology techniques that have only existed since the s.
