Japan synthetic world's first man-made DNA (map)

Keywords: world's first man-made DNA

Åœ — äº¬æ — ¶é — ' 8 July message, according to foreign media reports, Japan scientists said they had recently successfully synthesis out of the world's first man-made almost 100% of the DNA molecule. [] Newsletter: this new technology will not only help to improve the gene therapy methods, even capable of driving the future of nano-level computer or other high-tech equipment.

World's first man-made DNA molecule is born

In the forthcoming on July 23, the latest issue of the journal of the United States chemical Association, Japan scientists will announce their latest research results. For years, scientists have been exploring a storage density, and storage status more stable information carrier. As a result of deoxyribonucleic acid (DNA) is a great feature is the ability to carry large amounts of genetic material of living organisms. It amazing information storage capacity to scientists to enlightenment. They tried to develop artificial DNA as new information carriers. Use of synthetic DNA stored information, the so-called biological storage, this is a DNA full utilization of these characteristics. Scientists had previously also been first made use of DNA in Escherichia coli, then let the yeast cells to replicate DNA, then assemble them into a synthetic chromosome. Currently, DNA technology can be applied to manufacture simple circuit.

We all know that the DNA nucleotide sequence is the storage form of genetic information. DNA is generally through the four basic elements (nucleotide) encodes the protein determines the order of amino acids in proteins. Prior to this, there are some scientists use artificial materials synthesis the DNA molecule. Recently, Japan Toyama University Professor Masahiko Inoue will successfully adds four new artificial components into a DNA molecule of sugar-based framework, thereby creating an anomalous stable artificial double helix structure of DNA molecules, mimicking natural DNA. The structure and normal DNA double-helix structure are extremely similar. Compared with ordinary DNA, artificial DNA molecular structure is right Helix, and extremely easy to form a triple helix structure. DNA base pairing by 4 to copy the code, so dominant genes cells function and development. Other scientists with less artificial bases created a DNA molecule.

This artificial DNA structure have chemical characteristics and exceptional stability, will make biotechnology and material widely possible. Artificial DNA technology will be applied to future cellular gene system, this system has the information store and extended functionality. This may be able to provide future DNA computer information storage technology provides theoretical reference. Like natural DNA, this new artificial DNA is the right structure, however, there are some molecules are easily formed 3 spiral structure. The unique structure of their chemical characteristics and a high degree of stability for the development of new biotechnology materials and applications provide unprecedented possibilities.

Available artificial DNA to create new bio

As early as 50 years ago, scientists have begun to try in the synthesis of DNA in vitro, they take a variety of common chemical elements together to create the most unique molecular life. United States researchers are now ready to cross a huge obstacle: completely artificial DNA creation creature. Scientists have synthesis out of the world's first completely artificial chromosome-length strings in full in the laboratory synthesis of DNA, including microbial survival and reproduction of all directives are required.

Scientists hope that next year the chromosomes to a cell, it is expected that the chromosomes in the cells "to start", this is like the software downloaded from the Internet, and then the "trick" the wait command execution of cells. Although the first man-made chromosome and natural chromosomes are exactly the same, but scientists are some of the other chromosomes synthesis, these chromosomes to create unprecedented bio. Scientists and philosophers are of the view that the creation of artificial biological DNA will be a watershed event, meaning it fuzzy natural biological and artificial distinction between products so that people have to rethink what makes a thing called life.

However, this is the universe with unprecedented control of just philosophical questions. Scientists, terrorists and other creative people will create a kind of biological? how to curb these individuals can be self-replicating? create artificial life's basic tools of patents will return who all? security concerns are also growing. Already several scientists succeeded in synthesizing the artificial viruses. Mankind will soon have the ability to man-made bacteria. And viruses, bacteria can live outside of the environment in the survival and reproduction. This causes people to pollution, infections and potential hazards of new worries.
