Topic: Genetic manipulation


In the News (Tue 29 Dec 09)

  
  Soy Info Online!
Because it was not the lectin in the potatoes, but the genetic manipulation process itself which led to toxicity, similar results might be seen in animals or humans fed genetically-manipulated soy, canola, and corn over a long period of time (i.e., years or decades).
The same hazards may or may not be found in genetically manipulated soy, canola, etc. It is prudent to assume that all genetically manipulated ingredients have the same slow toxic effects until long-term, independent research can be conducted on each genetically manipulated crop.
There is a very serious danger of pollen from these manipulated crops infecting normal crops of the same species or of different species leading to the unintentional ingestion of drugs by the general population.

  Genetic engineering
Genetic engineering is inherently hazardous, because it depends on designing artificial vectors to cross all species barriers, greatly increasing the potential for generating new viral and bacterial pathogens by horizontal gene transfer and recombination.
This very danger persuaded the first genetic engineers to declare a moratorium on their own work in 1975; but pressures to go ahead with commercial exploitation led to regulatory guidelines that were drawn up largely on the basis of assumptions.
Genetic tests are actually poor predictors for the condition of any individual; the same gene will have different effects from individual to individual because their other genes are different.

 Council for Responsible Genetics
As genetic tests become simpler to administer and their use expands, a growing number of individuals are being stigmatized on the basis of their genetic makeup.
Meanwhile the exaggerated emphasis on genetic diagnoses is not without its dangers because it draws attention away from the social measures that are needed in order to ameliorate most diseases, including equitable access to health care.
Recent developments in human genetic science and the technology of testing are not identifying new costly diseases that were not previously accounted for by the insurance industry’s actuarial data.

 GENETIC ENGINEERING
Genetic engineering is the process of taking genes and segments of DNA from one species and putting them into another species, thus breaking the species barrier and artificially modifying the DNA of various species.
Genetic manipulation is most commonly used to transfer desirable qualities from one organism to another to improve the ability of other species to serve humankind.
The first field test of these genetically modified bacteria was conducted in 1987, on a plot of strawberry plants, and similar experiments on potatoes showed that the gene-spliced bacteria were effective in establishing themselves on the plants and, later in the season, in preventing ice formation during periods of light frost (Levine).

 Genetic engineering: what is genetic engineering?
Genetic engineering is the alteration of genetic code by artificial means, and is therefore different from traditional selective breeding.
Genetic engineering works because there is one language of life: human genes work in bacteria, monkey genes work in mice and earthworms.
Genetic engineering in its fullest form would result in the child produced having unique genes - as a result of laboratory interference, and therefore the child will not be an identikit twin.

 Vegetarian News - Genetic Engineering: Can it be all that bad ? Ask the animals !
Genetically manipulating plants to make them more pesticide-resistant is definitely not an ecologically meaningful way to produce healthy food.
But genetically interfering with our food to enhance their nutritional value without endangering our health and to reduce or eliminate the dependence on pesticides and fertilizers may very well be acceptable.
If genetic engineering is here to stay, we might be better off making sure that more and more members of the scientific community will be of the Goldman-type, which is to say, realistically, ethically and ecologically conscious vegetarian, near-vegan, and even better vegans.

 ADCHALLENGES FOR Genetic Manipulation in Animals
DNA microinjection is an inefficient and highly random vehicle for genetic manipulation, and may be complicated by transgene silencing, inappropriate transgene expression, and tissue variegation (8).
Genetic manipulation in chickens is much more technically complex due to the inaccessibility of the earliest stages of embryo development (17).
While genetically manipulated nuclei have already been used for nuclear transfer (26), the true test of the combined technology will be the generation of animals with complex deletions and/or additions.

 Geneinfo - Genetic engineering and Gene therapy
Genetic knowledge is indeed rapidly expanding, but most research centers around understanding the content and function of the human genome; less applies to the manipulation of human genetic material.
The basic strategy is to place the new genetic material (for example, a gene for a new desired function) into the cell, and use the cell's natural machinery to integrate this material into the genome.
Genetic manipulation of some laboratory animals, such as flies and mice, is also routinely used in research.

 Genetic Engineering
'Genetic engineering' or genetic manipulation as it should properly be called, relies essentially on the ability to manipulate molecules in vitro.
In fact, the genetic code is not completely universal - there are minor differences in the codons which are recognised ∧ used by different groups of organisms, e.g.

 What's Next In Science & Technology - Genetic manipulation modifies oil created by plant enzyme - Potential ...
Using genetic manipulation to modify the activity of a plant enzyme, researchers at the U.S. Department of Energy's Brookhaven National Laboratory have converted an unsaturated oil in the seeds of a temperate plant to the more saturated kind usually found in tropical plants.
The genetic manipulations that reduced KASII activity resulted in a seven-fold increase in 16-carbon unsaturated fatty acids — up to an unprecedented 53 percent — in the temperate Arabidopsis plant seed oils.
"These results demonstrate that manipulation of a single enzyme's activity is sufficient to convert the seed oil composition of Arabidopsis from that of a typical temperate pant to that of a tropical palm-like oil," Shanklin said.

 Atlantis, Alien Visitation & Genetic Manipulation - Michael Tsarion
Their genetic interference of the Earth Races resulted in several hybrid creatures, one of whom I will refer to as "Homo Atlantis." Each and every living "Adamic" human, of the last 10 millennia or more, is descended from this exceptional being.
The end-game of the visiting alien race and their descendants is being played out in the present "Silicon Age." It swiftly and relentlessly advances while most of us, preoccupied with our domestic and professional roles, have little time or energy to speculate how the multifarious phenomena of our world came into being.
Adroit manipulation from those within the echelons of power make quite certain that our attention is rarely focused on the law-makers and those in control of the economy, military, media and technology of the world.

 Genetic Manipulation in Nutrition, Metabolism, and Obesity Research - Science - RedOrbit
