(Worthy News) - Researchers at The Scripps Research Institute (TSRI) claim to have created the first stable semisynthetic organism with extra bases added to its genetic code. The single-celled organism is also able to continually replicate the synthetic base pair as it divides, which could mean that future synthetic organisms may be able to carry extra genetic information in their DNA sequences indefinitely.

The team from TSRI have added two synthetic bases that they call "X" and "Y" into the genetic code of a E.coli carrier organism – a single-cell bacteria – and then chemically tweaked it to live, replicate, and survive with the extra DNA molecules intact.

"We've made this semisynthetic organism more life-like," said Professor Floyd Romesberg, senior author of the new study. "We can now get the light of life to stay on. That suggests that all of life's processes can be subject to manipulation." [ Source ]

  1. sounds scary to me. Remember the doubling effect. You start out with one, and it doubles, and then doubles again, and continues to double for 18 more times there will be over a million of them. 20 more time and the number is too big for my calculator! and have these cells figured out what they want to do in life yet?
