SYNTHETIC GENOME

Rui Barbosa, PhD (U. Grenoble, France), Founder of the First Humanity+ Portuguese Chapter, transhumanismo@sapo.pt.

 

According to Discovery (1), “Scientists discovered a more efficient way to build a Synthetic Genome that could one day push the creation of synthetic life”.

 

As already said in our previous chronicle, the main difference between synthetic Life and “Artificial Life” is: synthetic life consists of synthesizing new forms of life from elements of the natural life, whereas Artificial Life intends to build simulations of Life from zero. “The method of development of the Synthetic Genome is already being used to help to develop biofuels of the next generation and biochemical materials in the laboratories of the controversial Scientist Craig Venter. Venter “greeted” forms of artificial life as a potential remedy for Illness and Global warming, but the perspective is highly controversial and raises a warm debate on the potential ramifications and the ethics of the engineering of artificial life”.

 

“In an article published in Science (2), the Venter' s team described the synthesis of the entire genome of the bacterium “Mycoplasma genitalium” from laboratory chemicals. … Venter said it was the largest artificial sequence ever made, 20 times longer than any previous attempt.

 

The team at the J Craig Venter Institute (JCVI) in Maryland is working on the final step to ‘create life’ transplanting the synthetic DNA into a cell in the hope that it will ‘boot up’ the cell and take control of its growth and reproduction.

 

The Scientists, lead by the Nobel Hamilton Smith, began by building long strands of DNA, each a copy of about a quarter of the whole M genitalium genome. These were inserted into levedura cells, which coseram stitched together the strands to make clones of the whole genome, named M genitalium JCVI-1.0.

 

The next step is to insert the synthetic chromosome into a cell, so that it can reproduce and become a new life form. Venter's team has already demonstrated that transplanting the genome of one type of bacterium into the cell of another can change the cell's species, a process his team will now use with the new synthetic chromosome.“

 

Therefore, it should be possible to create new (synthetic) species. 

 

The Nobel Hamilton Smith said that producing the artificial genome was like finishing the operating system of a computer. ‘By itself, it doesn't do anything, but when you install it on a computer, then you have a working computer system. It's the same with the genome: the genome is the operating system for a cell and the cytoplasm is the hardware that's required to run that genome’.

 

The work comes out of a larger JCVI effort to discover the minimum number of genes needed for a life form. In its natural state, M genitalium has 485 genes, 100 of which have been found to be non-essential. Synthetic biologists want to use this information to create the most efficient form of life possible, with the fewest genes needed to allow the organism to grow, replicate and proliferate.

 

Venter said there were two main reasons for the work. ‘One is trying to understand the minimal operating system of a cell and to understand basic biology. If these experiments are successful we could enter a new design phase of biology by actually constructing chromosomes of a specific nature for a more specific purpose.’"

 

It would be born thus a new derivation of Life, resultant of the manipulation by human being with sight to serve human designs. Designer Organisms have an enormous potential to create alternative sources of energy or to attack the climatic changes through the absorption of carbon dioxide.
