Nowadays, DNA technologies are getting a new panacea for any issue in the world – scientists trying to fight against a lot of diseases, they are developing and growing new fruit and vegetable variety as well as new breeds of animals. Personally, from my point of view, I agree that it is a very serious and unsafe realm because we have integrated something extraneous into a living organism and nobody knows about the future of him. Whereas, we have got many positive features due to results of improvements in genetic science – possibilities to treat serious illness, producing new goods and much more diverse fauna and fauna.
