The researchers copied an existing bacterial genome. They sequenced its genetic code and then used "synthesis machines" to chemically construct a copy.
Dr Venter told BBC News: "We've now been able to take our synthetic chromosome and transplant it into a recipient cell - a different organism.
"As soon as this new software goes into the cell, the cell reads [it] and converts into the species specified in that genetic code."
The new bacteria replicated over a billion times, producing copies that contained and were controlled by the constructed, synthetic DNA.
"This is the first time any synthetic DNA has been in complete control of a cell," said Dr Venter.
God must be so pissed right now.
Thanks to Joe, Kaz, J tothe T, Lord Tarl, Aaron, jeremy, GingerJohn, Justin, WillC, Schmaltz, james, David, Choma, Fortune and crawfy, who have all tried creating artificial life by procreating with sex dolls. ROFLWUT?!
