Creation of Synthetic organisms with new genetic code

[Kisito]

Californian biologists have announced have created a bacterium with a genetic code of a new genre invented by man. Another alphabet, enriched life . Technical prowess ? An uncontrollable madness tomorrow ? " First life with " alien "DNA " as Nature publishes the first . The journal adds : An engineered bacterium is ble to copy DNA That contains unnatural genetic letters .

English is always more effective to say , synthetically scary . " Scientists Add to DNA 's Alphabet Letters , Raising Hope and Fear " says The New York Times (Andrew Pollack ) (see here)

With the exception of the World and Slate.fr (disclaimer ) French media have shown little interest in the subject. Bridge May 8 ? For now , remember these names : Denis A. Malyshev and Floyd Romesberg . These biologists working at the Scripps Research Institute in La Jolla ( California ) . With six of their colleagues they have announced another step , historical, in the manipulation of living . The team therefore sign in Nature a communication that could be a milestone in the history of biology ( 1).

They announced the creation of a carrier of a genetic heritage that has never existed since the beginning of life on Earth bacterium bacterium whose genetic code is not only consisting of "four letters of the alphabet life " four " nitrogenous bases " A, T, C , G structuring the famous helix of DNA . But a bacterium having therein four "letters" associated with two other synthetic , created by U.S. researchers. It will soon write a sequel to Gattaca . Source : Jeanyvesnau.com, le 8 Mai 2014

From Bacteria to People: Slavery in Disguise​

Story at a glance:

• Today, genetically modified microbes are a major medium for the industrial production of chemical substances, foods, medicines, therapeutic proteins, etc.
• The term to watch out for is “precision fermentation”
• The National Bioengineered Food Disclosure Standard does not require these foods to be labeled as GMO because they do not contain the genetically engineered organisms, they are just produced by them
• Microorganisms, including genetically modified ones, also play a role in industrial production
• Another growing area is bacterial biosensors. They are based on programing bacterial cells (typically through genetic engineering) to recognize and generate a measurable signal in response to a specific molecule
