What is transgenic
Do you really understand gm?
What is transgenic, what is genes, and what are the genes that are made up of? Are we going to take the gene and absorb the information directly?
What is a gene?
Genes actually refer to a genetic material.
Heredity, as the name suggests, is something that can be passed on to future generations, which is what all living things can pass on to future generations.
For us, livestock and crops, genes are the DNA molecules in our bodies.
What is DNA? It's essentially an organic matter, made up of covalent bonds, like the starch we eat, but it's a lot more information than the starch complex.
Here said that like with the computer of 010101 information of binary code, this information is only organisms organelles tissue can identify and response to it, such as meat long hair.
It is also a kind of sugar, which is essentially like a special kind of starch.
If we ate the cow's genes, would we be the same as the cows?
The answer, of course, is no.
Just as the previous gene is actually a special kind of starch, you eat starch and finally not all become blood sugar!
Gene that is to say, in fact it is hard to through our digestive system, in the small intestine most genes has become a very simple chemical molecules, which can express the information of genetic/nothing, because the entire order has been disrupted.
That means no matter what information you store, after digestion, the information is washed away, and how it affects people.
Of course, the present study found that vegetable or meat small RNA remain stable, has not been degraded after cooking, can be absorbed into the body through the gastrointestinal, will also be involved in the regulation of physiological function, the specific impact now has not been effective evaluation of small RNA's main function is to participate in gene regulation or affect the apparent modification.
But the mechanism for the introduction of small rnas and their effects has evolved over hundreds of millions of years, not recently.
What is transgenic
Genetically modified (gm) is by molecular biology technology transfer some useful genes into crops or livestock, is to write a message in their DNA, the information stored in DNA, the same will also be digested, so no matter you are what kind of information, the digestive system's anyway.
Sexual reproduction is also belong to a kind of more generalized gm, both sides of the gene will fuses in together, will happen some gene transfer (that is, to the mother's genes from the father's genes - swap genes).
Many ornamental goldfish are also cultivated by artificial breeding, which is also a kind of transgenic only, which is more natural and more random time.
Let's look at some data:
The average gmo crop increased by 22 percent, reduced pesticide use by 37 percent, reduced pesticide costs by 39 percent, increased production cost by 3 percent, and increased profit by 68 percent. Developing countries benefited more than developed countries.
Our genetically modified tomato today is more than 100 times larger than the original currant tomato, and there are 18 major genes that have changed.
In the process of domestication, tubers are dozens of times larger, and the shape becomes more regular and easy for us to eat.
The national academy of sciences, national academy of engineering, as well as the national medical school called on more than 50 experts committee of experts, 2 years, with the 388 - page report, review of more than 900 studies, summarizes the birth of genetically modified (gm) crops in 20 years of data.
The conclusion: genetically modified foods do not increase the risk of human health compared to ordinary food.
In late June 2016, a group of 110 Nobel laureates issued an open letter calling on greenpeace to abandon its reversed position.
