Transgenic is the grafting of genes from one species to another, at which point we can obtain a life organism that mixes the genes of different species, and this life form will produce some characteristics of the species that provide genes in the process of growth. If this technology is applied to plants, then the result is a genetically modified plant; If this technology is applied to animals, the result is genetically modified animals. Of course, there will also be genetically modified species between animals and plants, humans and animals and plants.
The direct result of transgenic technology is the creation of new species. For example, grafting the genes of tomatoes onto the genes of potatoes can produce a plant that bears tomatoes on the ground and potatoes grow below the ground, which can greatly improve the efficiency of the use of increasingly scarce land. However, the tomatoes and potatoes grown in this new plant species are too small to be used in agriculture.
When this problem is solved in the future, this species will be very useful to us.

Genetically modified technology has been recognized as an effective means to solve the problems that are difficult to be solved by traditional breeding technology, and is one of the modern molecular breeding technologies commonly used in developed countries. At present, the genetically modified insect-resistant and herbicide-resistant crops cultivated by scientists have been widely promoted and applied, and a series of economic, social and ecological benefits have been achieved in increasing yields, increasing incomes, and protecting the environment. It can be said that genetically modified technology can not only directly benefit producers and consumers, but also has important potential to solve the world's resource shortage and energy crisis.

The yield is large, the plant is resistant to disease, but it is a technology that affects fertility and is very annoying. Don't like Monsanto's GMO.

There are good and bad, and good and bad are bicompatible.

Genetically modified technology is a technology that causes the heritability and modification of organism traits by introducing the expression of genes.
Knowledge of genetically modified technology:
Genetically modified technology uses molecular biology technology to transfer the genes of certain organisms to other species, modify the genetic material of organisms, and transform the organisms whose genetic material has been modified into the target of human needs in terms of traits, nutrition and consumption quality; The world's first transgenic plant was a tobacco containing antibiotic antibodies to the causta, which was successfully cultivated in 1983; The world's first genetically modified food was a genetically modified late-maturing tomato, which was put on the U.S. market in 1993; Genetically modified technology can be divided into artificial transgenic technology and natural key Zheng Tan transgenic technology according to the pathway, and can be divided into plant transgenic technology, animal transgenic technology and microbial genetic recombination technology according to the object; Genetically modified technology has a wide range of application prospects in many fields such as agricultural production, animal feeding and medical research.

Medically. Genetically modified technology has a wide range of applications in medicine. Animal transgenic technology can create animal models for diagnosing and improving human disease, overcoming the limitations of relying solely on natural mutants.
Genetically modified technology is also applied to the production of protein peptide drugs, such as the production of insulin, interferon, immunoglobulin, erythrocyte auxin, urokinase, human hemoglobin, human epidermal growth factor, granulocytes and other rare drugs.
Industrially. The application in the industrial field mainly refers to the application in the food industry, mainly including: the improvement of industrial fermented food strains such as yeast and lactic acid bacteria; production of food additives and processing aids; The manufacture of health care ingredients or effective factors that are beneficial to human health, and genetically modified animals and plants carrying different target genes can become a resource-rich drug reservoir for various incurable diseases of human beings.
environmental protection.
DNA probes can detect viruses, bacteria and other contamination in the environment very sensitively, and are not easy to die in large quantities due to environmental pollution, and can even absorb and transform pollutants. Normally, a bacterium can only decompose one hydrocarbon in oil, and "superbugs" that have been successfully bred by genetic engineering can decompose a variety of hydrocarbon compounds in petroleum.
I hope it's not genetically modified.
First of all, it is necessary to understand the principle of genetic alteration, mutations, radioactive elements, which must not occur in food. >>>More
Eating genetically modified foods is no safer than eating pesticide residues.
You are on the right side, in fact already victorious, unless your IQ is too low, it is impossible to fail! A mainstream scientific community has already made up its mind, and the opposition will not be allowed to overturn it. >>>More
No, genetically modified varieties are not so easy to market. >>>More
