Can formate the mankind with the dead material
Greater life project after clone technology The scientist disassembles the bacterium ring upon ring, keep dismantling until the gene that the life needs. Find a simple life only takes 350 genes The artificial living beings will be devils, created and can not control? When the surprising discovery at end of the century comes in A.D. 2000, the mankind suddenly found the understanding of life will be rewritten again over the years. Cloned the birth of the sheep in 1997, one was not that embryo's cells duplicated the life on making the mankind utilize organism; Only the new discovery two years later, will make the mankind utilize the dead material to create the new life. The newest one of authoritative scientific publication Science of the world reports this surprising discovery, the scientist has already found and formed the genetic quantity that the life needs. This news, like sending and value the scale bomb, sensational scientific circles. People realize, this means the scientist can be by made in the laboratory and born in the life as the chemical material of the lifing. The research institute of genome of Maryland State of U.S.A. disassembles a kind of bacterium ring upon ring, keep dismantling until the gene that the life needs. The scientists find, it needs 265 to 350 genes at least to form a simple life, these genes about 300 pieces are building and constructing life entity's minimum molecule order collection. The geneticist of this genetic research institute Dr. Craig and Venter says, this research is the set of using all genes of organism, namely genome (genome) ,Redefine the life. This kind of bacterium that the scientist studies survives in human genitals and lung, it is the minimum organism in the world. It what disease, less than any other known living beings the genetic numbers sucked does it will bring to human body. Human genetic number, between 80000 and 140000, and there are 480 this kind of bacterium. Craig and Venter,et al. makes the gene in the bacterium lose activity one by one, if bacterium's death, it is necessary that prove this gene killed the bacterium survives, through to a large number of test of bacterium, they find the bacterium survive genes needed. Because this kind of bacterium is the simplest life form, the genetic quantity that it needs is the genetic quantity that a life needs. Science still reports, analyzed to find, in the essential gene of this kind of bacterium, the functions of 100 genes are not yet clear at present. The existence of these unknown but essential genes, indicate the mankind has not found out about every thing about the basic life function yet. How did the life produce? Professor Zhu LiHuang of Ins of Genetics,Academia Sinica says when being interviewed by staff reporter, this finds it is the mankind that explores a milestone in the life course. Present genetic engineering but the transformation has already had one or more biological genes, and this research can use the synthetic and new living beings of gene of an array, open history that the mankind formates the life. The origin of the life is an old and mysterious topic. Up until now, the mankind can't really find the secret that the life produces yet. Present research showed, the life on the earth was formed gradually through the long-term natural evolution. The scientist infers, the primitive atmosphere on the earth has formed the organic matter under photoelectric function, later evolved into a primitive life. In 1955, University of Chicago carried on the simulation experiment of the origin of life, through discharging to the primitive atmosphere for a long time, have formated amino acid in the simplest biological molecule form. Also the scientist thinks, the birth of the life may come from the bombardment of the earth of aerolite beyond the heavens, the scientist has really found the organic matter in the aerolite, including forming all basic key elements of the material of life on earth. Most early microorganism evolve from, 600 million years ago, live in ocean probably at the the earth. 400 million years ago, the living beings mounted the land from the ocean gradually, formed amphibian and reptile, develop mammal and the mankind finally. The existing life forms in the so long evolution course on the earth, have gone through a lot of the rise and decline to replace too during that time. Though mankind have clarify all secret of origin of life, mankind already can try like the intersection of the earth and big life of coming into being that neglect born, formate out the brand-new life. The scientist will be acted " God " ? U.S.A. someone suggest scientist can produce the artificial bacterium in the laboratory chemical material to have life already, in order to verify the above-mentioned discovery. Craig Dr. Venter says: "Come, say we might need, formate one genome, see it can produce real life entity technically. Obviously, this is sure to create a new variety life that never exists. If we can really understand and have a life equation, that will be a far-reaching break-through - --And you must understand, even there are not 1 million that have 1,000 different equations that exist. " Someone prophesies: The scientist is acted " God " Creating the life will come true sooner or later, a lot of people among us can see the emergence of this in one's remaining years. In fact, according to this discovery, a simple life entity of artificial synthesis is easy to be realized technically. Zhu LiHuang Professor estimate in future several year, artificial synthesis some simple life possible, and should create more complicated life. Theoretically, once the secret of the human gene is totally untied, it is possible to formate the mankind with the dead material. The key problem is, the mankind should go to create a kind of brand-new life that has never existed. Dr. Venter says: "Before there are extensive debates on this questioning, we will not carry on this experiment. " Why will the mankind formate a new life not existing? This is really that one is worth discussing the issue that and think deeply about extensively. The scientist says, this kind of research helps people to further understand the origin of life. Dr. Venter points out, this technology may be countless and practical and having specially using microorganisms of commercial value, for example remove the poisonous filth or solve the moisture into hydrogen and oxygen to make into the regenerated energy. If rational application, formating the life will become good news of the human society. But such brand-new life (bacterium) Release out, who knows what great influence it can produce to present whole ecosystem? Professor Zhu LiHuang points out, it is certain to influence the existing life. The existing ecosystem evolved to take shape naturally for a long time, and it is brand-new to formate the life, its influence produced is unexpected too, so this kind of experiment must be close Go on in the environment. It is not that the scientist creates the life in the laboratory, people will inevitablely launch fierce dispute. Though this technology faces the panhuman morals to judge, the mankind explores the life Secret
