Genetics: Creating a cell with synthetic DNA
United States - John Craig Venter, an American biologist shows for his research in genome sequencing, has managed his teams to create the first bacterium with a fully synthetic genome.

This bacterium has been made from the sequencing of the genome of the bacterium Mycoplasma mycoides. It's been 15 years since researchers at the J. Craig Venter Institute in Maryland, harnessed to the task. The cell contains more than one million base pairs, which is low compared to six billion contained in the human genome.

This is a great advance in the field of genetics, this research could lead to the design of artificial life forms that could help produce biofuels or pharmaceuticals. Important ethical issues arise, however, due to possible drifts around this technique.

probably can expect a human with synthetic DNA..
