The newest era of biotechnologies started in 1938, when the first plants with alien genes built in their DNA-chain were raised in the scientific laboratory of the American company Monsanto. And in 1994 the first GM-tomatoes appeared in sale. Because of the gene of coldnessproof, taken from a flat-fish, they can be kept green in a cool place for a long time but become red in a warm place. In 1995 American companies started growing GM-soya.            A geneticist, which has got some kinds of ferments, can "cut" and "sew together" some parts of DNA in a particular place, building into it a gene he needs. This construction then is built in a cell of a host.            The work of the gene and the construction can be regulated. They can be turned on and off. They can be delayed from DNA.            The transference of this genetic constructions can be produced with the help of agribacteria. In the nature they infect the plants providing and regulating the growth of tumours transferring their genes in the DNA of the plants. To create GM-plants the scientists use the special types of these bacteria which can transfer the necessary genes into the plants.            The transgenetic plants are grown in the laboratories first and then on the experimental fields. After some obligatory security tests the plants can be recommended for the sale.            Since the middle of 1990s GM-plants have been grown in Argentina, France, China, India, Mexico, the USA and Canada. They were potato, corn, tomato, long keeping water melon,cotton, soya and rape. The transgenetic rice is almost ready to be applied. We know about the successful expriments when scientists built a vegetable gene into an animal gene in order to get vegetable fat.            In 2003 the prohibition on working out and usage of the GM-products in Europe was delayed. In Russia the growing of transgenetic sorts and creating the new ones is prohibited yet. But the import and the usage of GM-products are permitted, for example now we can buy one sort of soya, three sorts of corn, rape and beet. And there are no transgenetic products, which are used less than in three countries. The transgenetic soya which is put into meat products is permitted by the Ministry of Health. It is registered and used in sixteen countries and EEC countries are among them.            The very special attention is to be put at the criteria of the security while using the technologies of the genetic engineering.            In every particular case the authorities are led by different criteria which are variable such as the ways of the genetic modifying of organisms.            The production of food made of GM-organisms is a rather young industry. To appreciate true value of the harmlessness of the new products we need much time. A number of consumers' generations, who use products made of GMO, should change one another to understand it.            "In a human organism there are a lot of genes and we can't take into account all of their interactions ", - it is the main argument of the GM-technologies' opponents. Of course, we can't be sure about the ways of work and the purposes of all potato's genes.            When all the genes and albumens are studied, we'll be able to use necessary plants' and animals'peculiarities without doing any harm to them, us or nature.            The scientists worked, are working and will work. The genetic engineering is a very powerful tool which is not assimilated yet by the mankind. We should be responsible for making some decisions about permissions and prohibitions of the experiments with GMO.            You should decide yourself whether to use them or not. But it's better to have in mind the famous quotation: "Don't do any harm to your descendants".
