Researchers reveal ‘alien’ life using synthetic DNA according to : Daily Mail Online

as declared in It’s life, but not quite as we know it: A replicating ‘alien’ life-form has been made by scientists who introduced DNA molecules not found in nature to a common bacterium (stock image).
The modified E.coli bacteria was made by scientists who introduced DNA molecules not found in nature to a common bacterium.
An illustration of a DNA molecule is picturedIt started in 2008 when Dr Romesberg’s team of researchers succeeded in replicating unnatural base pairs in a test tube.
The plasmid DNA contained natural A-T and C-G base pairs together with a d5SICS-dNaM base pair.
They also managed to transcribe the semi-synthetic DNA into RNA – a first step towards translating a new genetic code into a protein.

Researchers reveal 'alien' life using synthetic DNA

referring to Scientists have engineered the first ever organism with synthetic DNA by expanding its genetic code, paving the way for creation of new and artificial life forms.
First, researchers built a new version of the nucleotide transporter – to carry the synthetic base pair and insert into the bacteria’s DNA.
Since then, the researchers have been working on genetically modifying the E. coli bacteria to take the synthetic base pair into their DNA code.

Scientists at The Scripps Research Institute (TSRI) bred E. coli microbes with an expanded, six-letter genetic code – developing a stable “semi-synthetic” organism in the laboratory.

Organisms created with synthetic DNA pave way for entirely new life forms

referring to From the moment life gained a foothold on Earth its story has been written in a DNA code of four letters.
Now, the first living organisms to thrive with an expanded genetic code have been made by researchers in work that paves the way for the creation and exploitation of entirely new life forms.
The end result, he says, is that the bugs can hold the new genetic material indefinitely.
The microbes are modified to absorb the new genetic material which the scientists make separately and then feed to the cells.
It took three crucial fixes for the microbes to survive and reliably pass on their new genetic material.
