Genetic modifications


Genetic modifications





Still genetic modifications and associated research of great interest among mid journalists, legislators, legal experts and even senior global giants. And different reasons and motives that make each party is interested in the subject, according to the wants, the charm of the idea and Ijaz fiction remains in control of the minds of everyone from supporters and opponents of this research, especially when you know that genetic modification techniques or genetic engineering radically and rapidly evolving and may incur for mankind the solution to many problems The dilemmas faced by man for hundreds of years.

No longer overcome the dilemma of diseases such as cancer, for example, or to secure ample amounts of food and agricultural crops for human gatherings ever-expanding impossible, but on the contrary seems to work on genetic modifications research will be the golden key, however, future generations, but the first appearance of agricultural products in accordance with these technologies will be faster Within five to ten years to come.

More in-depth knowledge and follow the story from the beginning leads to DNA, which is a small core molecules of the nucleotides may assembled for the installation of large molecules. There are nucleic acids in the cell nucleus, and the mission they are stores that and translate the genetic information for living things. In other words, you have the simple, tells a lot about you even before you were born, genetic map of your income. What is your shape, your color, diseases afflicting, your abilities, and everything is in the DNA.

In recent years, scientists have managed to decipher the DNA puzzle and translate all the genetic code that can be carried, but it came to this genetic code and design of customized genes control attempts. It means control animals born or even cultivated plants.


How gene modification technology emerged (CRISPR)?






This is the technology of the most famous discoveries have rights, and the reason is due to its reliability and ease of use, and flexibility to work through it on animals and plants. During several years ago, the work of a group of researchers in each of the universities of California, Berkeley, Harvard, the Massachusetts Institute of Technology, to develop a technique that allowed the scientists to make changes to the genome (genetic code of an organism) in an easy way and the objectives of the relative specific, which the form of a real shift in the way scientists think about genetic engineering

Ten years ago, the researchers managed in Kunming, capital of southwest China's Yunnan Province, from stud twin monkeys after the use of genetic changes in accordance with the unintended modification technique, known for short as genes (CRISPR). Monkeys born from the womb of a surrogate mother in which the fertilized egg, which is where scientists planted three specific genes.

Success of the experiment gave great hope of an important medical era allow the study of intractable benefit from experiments on monkeys diseases. He then moved attention to another aspect sensitive for humans is the food and the food. The giants began supporting research or specialized laboratories buy this new technology and the disposal of millions of dollars in the hope of controlling the technology will change the history of mankind.

When you visit one of the laboratories of the research centers, you'll find the same microscopic injection systems sensitive devices, usually with a needle a minute or two are headed to a bowl transparent crystal containing elements of the experience. These facilities are controlled by moving the levers and some disk.

Although the use of these devices both to animals or plants, the speed of achievement in changing the genetic specification remains very interesting. Scientists focused their efforts on the production and cultivation of new varieties of plants modified through technology modified genes (CRISPR) Vtm injection of foreign genetic components (for foreign origin of the plant). And then follow-up observation and study of the new plant begins operations in detail over the following months, and believe it or not the injection process takes no more than a few seconds.

New plant strains!




Operating range of protected cultivation houses and laboratories around the world on a workout technique (CRISPR), he managed a Chinese laboratory production of a new type of wheat resistant to fungi, as well as the rice was developed to give higher productivity than in per hectare. As in Britain, says the news that a group of scientists have succeeded in implementing the final adjustment of the gene in the plant barley is helping to organize the production of seeds and dedicated efforts towards the production of varieties resistant to drought.



Assisted technique (CRISPR) to provide easy and accurate way to change the genetic engineering of crops, hoping to give more food, and make it relevant properties resistant to drought and diseases more effectively.

This technology will provide a crucial opportunity to help scientists keep pace with microbes ever-evolving that attack crops, where he says Savian latency leader of the research team in the laboratory of Norwich, England, "we will need millions of dollars and many years of work if we are to apply the traditional methods because germs do not stay Kmahe fixed, but shift and change frequently, "team Savian try this technique on the potatoes, tomatoes, and other crops to combat fungal diseases but British scientist had participated in the development version of the technique modified genes (CRISPR) previously.



But the best he has done Savian and colleagues who worked on the plant barley, as well as the plant looks like broccoli, is to prove that the second generation of some genetically modified plants, did not contain any trace of nuclear intruder who used the first generation of plant construction for acid!

This research warned that the plants to which they apply these modification techniques will not be placed under existing neighborhoods organic control transgenic systems, which means they will avoid a lot of consumers' concerns about material genetically modified food.

Important that information sought and Investment Department and even speculation on shares of companies that do experiments include corn, peanuts, wheat and rice, where it is expected that the first modified seed sold within five years or less price.

It remains to point out that the US Department of Agriculture had previously refused to crops that have undergone modification gene technology insertion (TALENs), a technique similar to the technique modified genes (CRISPR), under the current legislation, but that everyone is rapid changes and important revisions to the laws that allow the cultivation of these crops in the European Union countries and China.
