• Why goats crossed with a spider, and whether the scientists were able to do it
Genetic engineers never cease to amaze the world with his achievements: in the press on a regular basis there are reports about the appearance of new species of living creatures that have modified DNA. One of the unusual goats, which introduced the genes of a spider. What scientists have done so and that they eventually got.
In Utah, the western United States, it is the original goat farm. Living here white goat in appearance indistinguishable from their counterparts, but milk from them quite extraordinary. After these goats inoculated gene spider zolotopryada, their milk was contain valuable protein, the so-called spider silk.
Arachnoid thread is a very valuable product due to the special elasticity, strength and lightness. It is widely used in medicine, in the production of durable and flexible materials, and many other valuable products. Needs in the web strands are growing, and its limited production is unable to meet all needs. It turned out that getting spider silk directly from the spiders themselves - quite a time-consuming and inefficient task. The fact that the right kind of spiders is very aggressive towards their own kind, which often can be observed among arachnids, spiders so breeding farms proved to be impossible. Then geneticists and came up with an incredible idea: to instill gene goats spiders and get valuable protein in their milk. When a few years ago the company began their experiments, they managed to get only three kids with altered genes. Of the seven genetically modified goats only three animals eventually became the owners of the genes spider zolotopryada. Today, in unusual farm live about 150 goats spiders, which population is increasing. Experiments have shown that milk from them can really get precious arachnoid thread. With these goats, scientists hope to make a breakthrough in the art of a unique material and has patented all of their discovery.
