Genetics is a relatively young science dealing with the study of the laws of heredity and variability of living organisms, which is especially interesting due to its bold and sometimes unexpected experiments.
Genetic Engineering
Genetic engineering is the latest biotechnology tool that allows you to obtain the required qualities of an organism by manipulating genes and introducing them into other organisms. The production of genetically modified crops, vegetables and grains, the production of human insulin, the breeding of new breeds of animals and new species of plants - all these are the results of the application of genetic engineering.
Loud genetic experiments
Eat a banana and get a hepatitis B vaccine at the same time? Indian scientists have recently published their work on the creation of this type of banana. At the same time, similar experiments were carried out with other fruits and vegetables, but in the end the choice was stopped on bananas. The new variety of bananas is a carrier of a weakened strain of the hepatitis B virus. According to scientists, once it enters the body with a sweet treat, the virus should cause an appropriate response in the body and contribute to the formation of immunity.
British researchers have gone even further, proposing to treat cancer with chicken eggs! A special breed of chicken, whose genes are mixed with human genes, contains a protein in its body that is an anticancer drug. Thus, eggs, which are mostly composed of this protein, can completely replace expensive anti-cancer drugs.
It is known that no artificial milk formula for babies can replace breast milk, inferior to it in both beneficial and nutritional properties. Chinese geneticists conducted an experiment that resulted in the appearance of cow's milk, almost identical to the milk of nursing mothers. The addition of cloned human genes to the DNA of a bovine embryo was intended to create a new breed of cows that give "human" milk.
The cow gives "mother's" milk, and the goat - milk and silk! An American scientist isolated the spider gene responsible for the creation of spider webs and crossed it with the gene of goats. As a result, the kids born from this goat retained the gene responsible for silk production.
Cabbage, which kills insect pests with scorpion venom, is by no means an invention of science fiction writers, but the result of the work of Chinese geneticists. A fish that grows by leaps and bounds is the result of a genetic experiment to introduce two genes into the salmon body at once: from the rapidly growing chinook salmon and burbot, which grows at any time of the year. The result is a type of salmon that is twice the size of normal and grows twice as fast, and this type of fish is officially approved for consumption.
All of these well-known genetic experiments were designed to make human life better and more convenient by providing him with cheap and easily obtainable food and medicine. However, scientists are still arguing how dangerous these experiments are and what unexpected consequences they can lead in the future.
