Genetic engineering nowadays

Genetic engineering is very popular subject to discuss nowadays. A lot of TV and radio programs talk about it quite often. I think everyone of us have heard something about it too. But if you ask someone in the street to explain what does it mean. Only some of them could do this. The biggest part all of all people even don’t know what does “Genetic engineering” mean. The term as “Genetic engineering” we can describe quite simple. It is an artificial introduction of changes to the genes in a cell. Genetic engineering is variously know as genetic modification or genetic manipulation too. All three terms mean the same thing.
Genetic engineering started lots of years ago and selective replanting was the first thing which leaded scientists to nowadays modern genetic engineering. The practice of selective replanting has been known since the dawn of agriculture. In the twentieths century Gregor Mendel took the concept of selective replanting and actually turned it into selective breeding. So all theories of heredity are attributed to him. And after his works everything started to develop faster. In 1952 the Deoxyribonucleic Acid (DNA) was discovered as a genetic material. So it with Mendel's early experiments paved the way for the future of genetic engineering. In 1969 the gene was discovered. In 1982 researchers succeeded in transferring in gene from one species of fruit fly to another. In 1987 scientists introduced a gene from a bacterial cell into tomato plants. And at last in 1990 scientist started to work on new very important project, which was called “Human genome project”. And after ten years hard work in 2000 they got all human genome.
Plants genetic engineering nowadays is quite common thing. We all go to supermarkets every day and buy a lot of food products. A lot of...
