NEW YORK — Life is a DNA software system system , genome scientist Craig Venter told a jammed auditorium here at the American Museum of Natural History Monday nighttime ( Oct. 21 ) . In his talk of the town , Venter offered a longsighted position of the creation and digitization of man-made life sentence .
Creating synthetic life is just a crowning achievement of Venter ’s life history and the evolution of the field of operation of biota . In 2000 , Venter led of one of the two teams that sequence the humangenome , the blueprint for lifetime . Then in 2010 , his team transplanted serviceman - made DNA into a bacterial cell to make thefirst synthetic organism .
To make a synthetic electric cell , Venter tell , he and his colleague had to find a way towrite the DNA software and boot it up . And this technology open up a host of hard-nosed diligence , he explains in his new book " Life at the Speed of Light " ( Viking Adult , 2013 ) , in which Venter narrate the story of these milestones and speculates on the future tense of biology in the digital eld .

biologic teleportation
His ideas only get more unusual from there . What if , Venter speculated , one could place a genome across thesolar systemat the speed of light , and restructure it on the other side ? For exercise , if a rover discoveredlife on Mars , it could sequence the life - manakin ’s deoxyribonucleic acid and beam the codification back to Earth , where scientists could rebuild the being .
Of of course , Venter was talk about simple living - forms such as bacterium . " We ’re not ready to beam humans across the universe anytime before long , " he said .
But the realism is still impressive . The power to synthesise life from its deoxyribonucleic acid alone could immensely accelerate vaccine output , Venter say . Scientists could sequence an go forth flu virus anywhere in the world , and send that successiveness over the Internet to pharmaceutic company that could develop a vaccine for it . Ultimately , he enunciate , people may be able to download genetic episode to a machine that produces vaccines in their own homes .
Venter and his colleagues have lay the grounding for these developments by modernise the tools needed to construct living cell .
Synthesizing life
The first stride , Venter explain , was making software that could build its own hardware . His team make asynthetic phage , a computer virus that infects bacteria , and injected that intoE. colibacteria cells . The jail cell incorporated the synthetic DNA into their genomes , and they started assembling bacteriophages . [ 5 Crazy Technologies That Are Revolutionizing Biotech ]
Venter ’s next undertaking was challenging : His team modified achromosomefrom the bacteriumMycoplasma mycoidesand inserted it into the cell of the bacteriumMycoplasma capricolum . To do that , his team had to make grow advanced new familial techniques .
Once inserted into the host , M. mycoides ' deoxyribonucleic acid initiate making instructions for enzyme that chewed up the legion bacteria ’s genome . The result ? " We graft the genome from one cellphone into another coinage , and in the procedure of doing that , exchange the one species into the other , " Venter said .
The last whole tone was to tack together an full bacterial chromosome and put that into a prison cell where it would double — no easy feat . To do that , Venter and his team created big clod of bacterial DNA and assemble these inside a yeast cubicle . After several roadblocks and years of trial - and - error , the scientist producedthe first synthetic cellin 2010 .
The synthetic genome check a " watermark " sequence that included the names of the scientists who worked on it . It also include inverted comma by physicists Richard Feynman and Robert Oppenheimer , and this quote by author James Joyce : " To live on , to err , to return , to triumph , to revivify aliveness out of life . "
Playing God ?
to that extent as the squad created an organism capable of thriving and self - replicating , Venter and his colleague had make life .
Were they play God ?
" In the restricted sense that we had express with this experimentation how God was unnecessary for the creation of raw life , I suppose that we were , " Venter write in his fresh book .
But for Venter , synthesize sprightliness is merely the logical event of years of genetic tinkering .
mod biological science was bear , Venter believes , when Austrian physicist Erwin Schrödinger gave a series of lectures title , " What is Life ? " in Dublin in 1943 . Schrödinger propose that chromosomes were a variety of " codification script , " which might be as simple as Morse codification .
In 1944 , three Canadian and American scientists — Oswald Avery , Colin MacLeod and Maclyn McCarty — perform an experimentation that provedDNA , and not protein , was the ancestral textile of cells . And in 1953 , American biologist James Watson and his British workfellow Francis Crick discover the structure of DNA , building on work by Rosalind Franklin and Maurice Wilkins .
The 1960s and seventies see Brobdingnagian advances in the understanding of DNA and recombinant DNA engineering . construct on these foundations , Venter ’s group and the in public funded Human Genome Project produced the first draft sequence of the human genome in 2000 .
