I am creating artificial life,declares US gene pionneer
正文:Craig Venter,the controversial DNA researcher involved in the race to decipher the human genetic code ,has built a synthetic chromosome out of laboratory chemicals and is poised to announce the creation of the first new artificial life form on Earth
The announcement,which is expected within weeks and could come as early as Monday at the annual meeting of his scientific institute in San Diego,California,will herald a giant leap forward in the development of designer grnomes,It is certain to provoke heated debate about the ethics of creating new species and could unlock the door to new energy sources and techniques to combat global warming.
Mr Venter told the Guardian he thought this landmark would be “a very important philosophical step in the history of our species.We are going from reading our genetic code to the ability to write it.That gives us the hypothetical ability to do things never contemplated before”.
The Guardian can reveal that a team of 20 top scientists assembled by Mr Venter,led by the Noble laurate Hamilton Smiith,has already constructed a synthetic chromosome,a feat of virtuoso bio-engineering never previously achieved.Using lab –made chemicals,they have painstakingly stitched together a chromosome that is 381 genes long and contains 580,000 base pairs of genetic code.
The DNA sequence is based on the bacterium Mycoplasma genitalium which the team pared down to the bare essentials neeeded to support life,removing a fifth of its gentic make-up.The wholly synthetically reconstructed chromosome,which the team have christened Mycoplasma laboratorium,has been watermarked with inks for easy recognition.
It is then transplanted into a living bacterial cell and in the final stage of the process it is expected to take control of the cell and in effect beome a new life form.The team of scientisits has already successfully transplanted the genome of one type of bacterium into the cell of another,effectively changing the cell’s species.Mr Venter said he was “100% confident ”the same technique would work for the artficially created chromosome.
The new life form will depend for its ability to replicate and metabolise on the molecular machinery of the cell into which it has been injected,and in that sense it will not be a wholly synthetic life form.However,its DNA will be artificial,and it is the DNA that controls the cell and is credited with being the building block of life.
Mr Venter believes designer gnomes have enormous positive potential if properly regulated.In the long-term,he hopes they could lead to aiternative energy sources previously unthinkable.Bacteria could be created,he speculates,that could help mop up excessive carbon dioxide,thus contributing to the solution to global warming,or produce fuels such as butane or propane made entirely from sugar.

克雷格·文特,备受争议的脱氧核糖核酸(DNA)的研究员参与比赛的遗传密码破译人类,已建立起一个合成染色体走出实验室化学品和宣布创造新的人工生命的形式在地球上
这项声明,预计将在几周内,有可能早在星期一召开的年会上,他的科学研究所加州圣地牙哥,将预示着一个巨大的飞跃发展grnomes设计师,这一定是引发了激烈辩论伦理的创造新的物种,打开门到新能源和技术来对抗全球变暖.
温特先生,他认为这告诉卫报的标志性将成为一个“非常重要的历史哲学的一步,我们物种我们要从阅读我们的基因编码的写作能力是.这使我们能够做的事情永远假设预期的".
家长可以显示一个20人的团队的顶尖科学家通过文特的带领下,高贵的laurate汉密尔顿Smiith,已经建造了一个合成染色体,这一壮举的演奏家生物在以前从未达到使用化学实验室,他们之前在刻意的染色体缝长和包含381基因遗传密码的580,000降到了现在的碱基对.
DNA序列是基于细菌的团队尿道支原体的刮下来学到neeeded支持生命,消除了五分之一的遗传化妆全面综合改造,球队已经染色体命名支原体laboratorium,已经与墨水印的简单识别.
然后将其移植到一个活细菌细胞,在最后阶段的过程,它预计需要控制的细胞,在一个新的生命形式的效果做…这个团队的scientisits已成功地移植了基因组的一种细菌进入细胞的变化,有效的细胞的物种文特表示,他“100%的信心”以相同的技术将为artficially创造的染色体.
这个新生命形式,它将能够复制并对分子机器上的细胞,它已被注射,从这个意义上说,它将不会是一个完全人造生命形式然而,它的脱氧核糖核酸(DNA)将人造,它是DNA中控制细胞和使用生命积木.
文特相信设计师侏儒拥有强大的积极合理调整潜力…在长期的,他希望他们能导致aiternative能源先前的不可思议的.细菌可以创造,他推测,这可能有助于吸收过多的二氧化碳,解决全球变暖的问题,或生产燃料丙烷了异丁烷或完全是由糖.这是我自己的理解,你看看行不行
好长啊、
