Every living organism consists of cells ranging from bacteria to higher mammals. Higher organisms are composed of organs, organs consist of tissues, tissues are composed of cells. All the properties of any organism are determined by its genome, which is in a cell (any cell of the organism).

According to some, the genome of the common flies and humans the same three quarters. Nothing surprising in this. The basis for genes is deoxyribonucleic acid - DNA carries all the information about the construction of all proteins and the biochemistry of the body, while the share of "external appearance" of the size and weight of an instance of species, apparently, is not so much. In short, Darwin is absolutely right and evolution at a certain stage, nodal binds and fly and man. And religion does not contradict this, because it just affirms the fact of creation of life by God, but not reglamentary the technology.

Gene and cell engineering (it's one concept) deals with the communication between the device DNA and hereditary properties of organisms. Of course, she is armed with such methods, which previously, for example, in the times of Mendel, and dare not dream.

A Method of cell engineering is at the present stage that specialists get fragments of DNA of different organisms and embed them into the DNA of an organism, is chosen as the object of study. This method in the language of scientists with a fondness for technical terms, called by expression of recombinant DNA. As tools are taken restrictase — special bacterial enzymes that can cleave DNA. They are called figuratively — biological knives.

Having obtained the desired gene (transgene), collected from the mentioned fragments, inserted it into a DNA molecule called a vector and transfer it into the cell, where it replicates (reproduces) itself or after Association with the “native” chromosome. Here great difficulties arise with the equipment, as the material must be entered in a microscopic cage of force, but without violating its integrity. There are many highly sophisticated methods, as the natural ways to do it. Of course, there is no mystery, it's just evolution, nothing provided, in contrast, has put a bunch of obstacles in the framework of natural selection.

Target, which carries cellular engineering: getting medicine, breeding of quality varieties of cultivated plants, creating new breeds of animals, and as the highest point — to rid our civilization of all diseases. Those who argue (don't want to call them bigots) need to keep in mind that only one synthetic insulin has saved and is saving millions of diabetics and prolong its life for decades!

Concerns about genetic engineering originate from the time of her birth in 1972, the year when the group P. Berg (USA) synthesized the first recombinant DNA of oncogenic monkey virus SV40 and E. coli. The last — Escherichia coli, without which man cannot live. And she has a virus that causes cancer. Scientists literally frightened, and do not even have to continue working at that moment. There was a long period of production research under the strict control of the state, comparable with the control over nuclear weapons.

Fortunately, the complexity and cost of biological genetic work of comparable complexity and cost, nuclear research, and therefore does not afford potential terrorists.

In reality, cell engineering it — a double-edged sword — it can give a person so much life, how much he wants, but it can wreak terrible misfortune for all living things. Do not argue, the reverse is not proven, and the "issue price" is known. It all depends on anyone with clean or dirty hands is cell engineering. And, for objective reasons, it can neither deny nor push forward. The development of science follows its internal laws.
