For the first time ever, scientists announced last week that they have finally successfully created an entire synthetic genome. Working diligently in the lab, scientists were able to stitch together the DNA of the smallest known free-living bacterium, Mycoplasma genitalium. The research is hailed as a groundbreaking event in genetic manipulation that will one day lead to the "routine" creation of synthetic genomes—possibly including chromosomes in larger animals like mammals.
This accomplishment marks the next big step in creating entire synthetic life forms. The new work is the second step in a three-step process, said research leader Hamilton Smith, a biologist and Nobel laureate at the J. Craig Venter Institute in Rockville, Maryland.
The first step was reported last year also by the same team at Venter's institute, with the successful transplantation of a genome from one species of bacteria into another, which effectively switched the organism’s identity.
