Researchers advance toward engineering "wildly new genome"
October 17, 2013
In two parallel projects, researchers have rewritten the genetic code of the bacterium E. coli. In the first study, they created a genetically and biochemically novel organism by erasing every example of a single codon from the entire genome. In the second, they tested whether all codons could be swapped to a synonymous codon in 42 separate genes, while eliminating every instance of 13 codons throughout each of those genes.

The National Science Foundation (NSF) is an independent federal agency that supports fundamental research and education across all fields of science and engineering. In fiscal year (FY) 2012, its budget was $7.0 billion. NSF funds reach all 50 states through grants to nearly 2,000 colleges, universities and other institutions. Each year, NSF receives about 50,000 competitive requests for funding, and makes about 11,500 new funding awards. NSF also awards about $593 million in professional and service contracts yearly.
