Regarding genetically modified organisms, what is genetically modified ?

The use of scientific means to extract the required genes from a certain organism, transfer them into another organism, and recombine them with the genes of another organism to produce specific substances with excellent genetic traits. Genetically modified technology can be used to breed new varieties and other things.

In fact, the exchange, transfer and alteration of genes are common phenomena in nature and an important force to promote biological evolution.

It is precisely because of genetic changes that species can continue to have new traits, and further development will produce new species, forming a gorgeous biodiversity in nature, and our world can be so colorful.

Genetically modified organisms are the use of engineering technology by scientists to transfer one or several genes of one organism into another organism, so that the latter organism can obtain new traits. For example, insect resistance genes are transferred to cotton, rice or corn to breed transgenic cotton, rice or corn that is resistant to insects such as cotton bollworm, leaf roller borer and corn borer.

Genetically modified technology has been called "one of the most rapidly applied major technologies in human history". Manipulation and transfer are generally well-defined genes with clear function and predictable offspring performance.

Spontaneous transgenic phenomena are also widespread in nature, such as cross-pollination, natural hybridization, and the natural transgenic system of Agrobacterium in the plant kingdom.

Genetically modified technology is used in various fields of society, including the use of genetically modified technology to improve crops, vaccines, food, etc. Foods containing genetically modified crop ingredients are called genetically modified foods and are as safe as non-genetically modified foods. The regulation of GMOs varies from country to country.

Technical classification. Plant transgenic technology.

Plant transgenic technology is to use cloning and other methods to insert foreign DNA into recipient cells, and the representative use methods such as vector-mediated method and direct DNA uptake method are used.

Animal transgenic technology.

Microinjection is the use of glass needles to inject DNA into the nucleus of animal embryos, and then transplant embryonic cells into the animal body to make it develop normally, which is a commonly used animal transgenic technology in the early days.

Somatic cell nuclear transfer is to first culture cells in vitro, select high-quality genes, and then transplant them into egg cells and then into the mother.

Every living thing in nature has different life characteristics, and the substances that maintain these life characteristics are the genes (DNA) in the nucleus. Genetically modified organisms (GMOs) are organisms that artificially modify their DNA to achieve a specific purpose. The usual practice is to extract a gene fragment of an organism with a special function and add it to the target organism through genetic technology.

Genetically modified crops are not much different in appearance and taste similar to natural crops, but some genetically modified crops have added genes that improve nutrients, while others can adapt to harsh natural environments and improve yield and quality.

According to incomplete statistics, in 1996, the cultivated area of genetically modified crops in the world was 1.7 million hectares, and in 2000 it increased to 44.2 million hectares, an increase of nearly 30 times in just four years. Among them, the cultivated area of genetically modified soybean and corn accounts for about 80% of the total cultivated area. In the food industry, soybeans and corn, as well as their processed products, are essential raw materials, and foods made from these genetically modified raw materials are also genetically modified foods.

Artificially implanting other genes into the cells of organisms to make them change, such as genetically modified vegetables and the like.
