Ever since researchers began deciphering DNA, they have wondered if they could use the sequences to
build synthetic genomes.
«They are going strong,» says biologist Jef Boeke of New York University, who helped lead the research as part of the Synthetic Yeast 2.0 project — an effort to
build a synthetic genome for yeast that would give scientists nearly complete control of it.

They
built up the
synthetic genome from 1078 units of approximately 1000 base pairs, assembling them into larger and larger units by a factor of ten each time, until they created the complete
genome of about 1.08 million base pairs after three such stages.
This takes them closer to creating microorganisms with
synthetic genomes that are purpose
built to carry out specific roles, such as making biofuels or hydrogen.
Last week, genomics pioneer Craig Venter announced that his team has passed an important milestone in its efforts to create a bacterial cell whose
genome is entirely
synthetic — constructed chemically from the
building blocks of DNA.
But while Venter's
synthetic genome will be housed within an existing bacterial cell, other scientists are aiming for the even more ambitious target of
building an entire living cell from the basic chemical ingredients.
Synthetic biology enables researchers to tackle a huge and diverse range of applied problems:
building a cell with the smallest possible
genome; synthesizing proteins with extra amino acids — more than the 20 found in nature; using bacteria to produce medicines previously too complex to synthesize; even decomposing living organisms into standard, off - the - shelf «biobricks» that can be assembled on demand.
«The idea of
building whole
genomes is one of the dreams and promises of
synthetic biology,» says Paul Freemont, a
synthetic biologist at Imperial College London, who is not involved in the work.
The team that
built the first
synthetic yeast chromosome has added five more chromosomes to their repertoire, totalling roughly a third of the organism's
genome.
But like others, Venter told the commission in oral testimony today that
synthetic biology is «very different from what's happened before» because scientists can now
build genomes from digital information and a DNA synthesizer.
It also offers an alternative to the approach used by biologist Craig Venter of
building a
genome from scratch to impart new properties to cells — laborious because even the smallest error kills the cell (see «Craig Venter: Why I put my name in
synthetic genomes «-RRB-.
For 15 years, J. Craig Venter has chased a dream: to
build a
genome from scratch and use it to make
synthetic life.
Scientists today announced that they have crafted a bacterial
genome from scratch, moving one step closer to creating entirely
synthetic life forms — living cells designed and
built by humans to carry out a diverse set of tasks ranging from manufacturing biofuels to sequestering carbon dioxide.
In May 2010, the J. Craig Venter Institute announced that its lab had
built the first
synthetic, self - replicating bacterial cell — that is, researchers inserted a
synthetic genome, which did not exactly match the DNA sequence of any natural
genome, into an existing working cell; the cell accepted the
synthetic genome and reproduced.
In 2012 he founded and is now Co-Director of the Concordia Centre for Applied

«This work highlights the power of combining advanced
genome editing and
synthetic DNA technologies to
build novel cells with unique characteristics,» said Dr. Gibson, Vice President, DNA Technologies, SGI; Associate Professor, JCVI.
The goal of Sc2.0 is to design,
build, assemble, and test the function of an entirely
synthetic designer yeast
genome.
