Speaking of , these yearsThere have been controversy.In fact, genetically modified crops must be listed with scientific evaluation and formal approval to ensure that the genetically modified products researched by scientists are safe.GM technology is professional, and the process is required to understand and understand, and we need to face it with a scientific attitude.So, what exactly is genetically modified?Why do bugs die when they eat insect -resistant protein?
What is genetically modified?G
The controversy about genetically modified has been existed in the past few years. To discuss this problem, it still needs to be returned to the principle of genetically modified.There is a correct judgment.In fact, GMI is a scientist using engineering technology to transfer one or more genes of one organism to another, so that the latter creature can get new traits .
However, the expression of genes also has "dialect".The genetic expression language of the body.Therefore, scientists must adjust the genetically modified creatures in the laboratory.
For example, the insect -resistant gene is turned into cotton and cultivated into genetically modified cotton with resistance to cotton bellworm. This technology is called genetic improvement, genetic modification, genetic engineering, etc. internationally translated into "genetically modified" during translation.
Will they be genetically genetically genetically genetically genetically genetically genetically genetically genetically genetically gene?G
The earliest misunderstanding of the genetically modified gene is "eating genetically modified food will be genetically modified", which still exists until today.Such misunderstandings are the same as "people eat pork" or "mule infertility, and people who eat mules will follow infertility."
So, in the GMO security assessment framework recommended by the WTO, there is no so -called "whether a person eats the genetically modified" related content, because this statement is not necessary for this statement.The imagination of some groups of biological knowledge is not a scientific issue.-
There are tens of thousands of genes in the food, one or more genes that are turned inLike genes, it was quickly digested in the stomach, and they did not have any chance to "move" our genes .
Why does the bugs die if they eat insect -resistant protein, and people eat it?G
This idea may be related to our impression of chemical pesticides.Many people think that chemical pesticides can not only kill insects and make people poisoning.But in fact, many things around us are things that are not blessed by other species, but humans are regarded as food, such as chocolate, which is delicious for us humans, but if cats and dogs eat it, they will be poisoned. Because of the different digestive abilities of different animals, the food that is different is different, which is a common phenomenon in nature. Dogs eat too much chocolate to poison because the dogs are difficult to cocoaine in chocolate, but people are easy, but no one questioned, "Dont eat chocolate dogs, can people eat it?"
As for why the bugs eat insect-resistant protein, it is the reason why insect-resistant protein is called insect-resistant protein.Insectal protein is only effective for specific pests, and has no effect on people and other mammals. Because there is no receptor in this protein in mammals, and the acidic gastrointestinal environment can be degraded and absorbed by these insect -resistant proteins.
Affected by complex factors, arguments about genetically modified may exist for a long time.Looking at the history of science and technology, every major disruptive theory and technological breakthrough may cause fierce debate. GM technology is strong, and the process is needed to understand and understand, and we need to face it with a scientific attitude.
