The term "biotechnology" was coined in 1919 by a Hungarian scholar Karl Ereki. Biotechnology means – "any product produced from raw materials by living organisms." In fact, biotechnology exist since ancient times. It was found that around 6000 bc, sumarityane and Babylonians used yeast for beer production. About 4000 bc Egyptians used yeast for baking bread, and used bacteria to create a Chinese yogurt. In the modern world, biotechnology is taking the countdown to the mid-1970's, when molecular biologists have developed methods for isolation and develop ways to identify and clone specific genes. These genes could manipulated in vitro, and implant in other organisms by "recombinant technology." At the dawn of modern biotechnology since 1977, when the biotech company Genetech examined the production of bacteria first human protein, somatostatin, by recombinant technology, then, for insulin and human growth hormone (HGH) were also produced similar methods. Biotechnology promises dramatic opening of the twenty-first century, especially in the areas of new drugs, antibiotics and medicines. Genetic manipulation of plants and animals are used for obtaining useful reagents, such as antibodies in milk and vaccines in potatoes.
The new "green revolution" in the field of biotechnology is to improve food crops. Currently being developed plants that produce their own nitrogen fertilizer, without pesticides. Other herbicide-resistant plants can eliminate weeds and improve productivity. But there is another side of biotechnology. Biotechnology, unfortunately, be used to develop biological weapons by increasing the virulence of pathogens.
