How to distinguish genetically modified soybeans? There are two kinds of opinions circulating on the Internet, and they are completely opposite.

Both of the above statements are wrong. Transgene is usually to transfer one or two target genes, and the expression level is generally not so high as to affect its physical properties. Conventional means can't detect it. At present, PCR and SOUTHEN BLOT are used at DNA level, RT-PCR and Northern blot are used at RNA level, and ELISA, western blot and test strip are used at protein level.

These methods are not easy to master, but the test paper of Bar gene and Bt gene is relatively easy. You can buy it from biochemical reagent company, then grind the beans into PBS buffer (when buying test paper), insert the test paper, and two bands appear, which is the corresponding transgenic soybean variety.

The query that "the navel of anti-glandular varieties planted in parts of northern Heilongjiang is pale yellow" seems untenable, because what I know is that the transgenic technology in China is very backward at present, and the transgenic technology in China is not as good as that of a Monsanto company in the United States, and there are no varieties that can be applied to the market at all. The best result that has been proved so far is just the creation of a certain quality resource. So if it is a domestic variety, don't expect it to be genetically modified.

As for the problem of "no germination", it is usually the phenomenon of soybean atavism (pure natural), which is called "hard fruit" in terminology, which means that the seed coat is impermeable to water and cannot be absorbed and germinated. If this is the result of transgenic plants and the obtained transgenic plants cannot be passed down, then the research is meaningless. It takes several years and a lot of human resources, but it only takes one year. It's a great irony.

Transgene (popular explanation)-the gene of a known organism in nature is transferred to another known organism, so that the latter can obtain the excellent characteristics of the former. For example, the bt gene of Bacillus thuringiensis (Gram-positive Agrobacterium, widely used as biological control engineering bacteria) is transferred into crops to make them resistant to insects.

"The harm of genetically modified organisms to human beings" is like transferring the genes of eggs to tomatoes, if you don't eat tomatoes and scramble eggs.

It took God six days to create the world and another day to rest. Although God is omnipotent, there are some defects in the created species, so researchers are committed to this. At first, it domesticated wild resources, then developed breeding technology, then carried out cross breeding and breeding, and now carried out molecular breeding and genetic modification. So researchers become jokes, deny the existence of God and become God's assistants. What is even more ridiculous is that, just like the ancient heroes in Greek legends, they flew too high and too close to the sun, and the wax on their wings was melted and fell to death alive. Many molecular biochemical reagent (such as dimethyl sulfoxide DMSO, ethidium bromide EB, diethyl pyrocarbonate DEPC, etc. ) are highly toxic, and they accumulate in researchers for a long time, which is harmful to researchers engaged in molecular biology research and their descendants (usually people in this industry will choose to stop the experiment for 3-6 months and have children). The saddest thing is that people who enjoy the fruits of each stage-the public-strongly oppose or even spit on researchers. The flame that burned Bruno in the Rome Flower Square never went out.

In the second half of the speech, some people are sensational in it, so I'm afraid it's not objective. Please forgive me.
