GMO
What are GMOs (Genetically modified organism)?
Is an organism whose genetic material has been modified through genetic engineering, and such changes would be impossible in nature as a result of reproduction.
GMOs can be plants, animals and microorganisms.
How is GMO made?
Let's remember the biology lessons at school. Perhaps some of you remember that the DNA molecule consists of 4 nitrogenous bases (adenine, thymine, guanine and cytosine). Remember those beautiful and colorful pictures of DNA that are twisted like spirals? Each section of such a spiral carries information about some quality of the organism. For example, about the sweetness of watermelon.
So, scientists clearly understand which parts of this spiral are responsible for sweetness. Using a special restriction enzyme, the gene and vector are cut like scissors. And with the help of another ligase enzyme, you can "glue" the pieces and get a different combination.
Why did scientists create GMOs?
No, not to poison all people, so that they all mutate!
The benefits of GM are as follows:
1.New varieties of plants are created that are resistant to an unfavorable environment (insects, climate, etc.)
2. The benefit arising from the first point is that the taste can be better, the plant or animal will grow better. This will feed the growing population of the planet.
3. Reducing the use of pesticides by more than 30%.
How it works? There is, for example, a variety of corn, which is stubbornly devoured by a harmful insect. With the help of GM, we changed the genes of this corn, and this corn variety no longer attracts insects. Therefore, we do not need to spray the plant with pesticides to protect against insects.
Are GM foods safe?
GM foods have been well researched for over 50 years! There are over 130 research projects that prove that biotechnology, including GM, is no more dangerous than traditional breeding methods.
No, I'm not crazy. The product after genetic modification does not differ from the "natural" one. The only difference is in their origin!!! Some are created in the laboratory, others in nature. And no, in the laboratory does not mean worse!!! In nature, mutations also occur without human participation. And even my grandmother in the garden also has mutations that you have no idea about. But in the course of testing GMOs, toxicity, allergenicity, resistance of the introduced gene and many other factors are investigated.
And finally, there is no strange gene from the eaten soybeans will not be able to integrate into your genes. To modify something, a complex technology is used, and it does not always work. And of course, our body has developed protective mechanisms by evolution.
