Scientists change an organism’s entire genome

In an advance that could help battle disease and create new biotech materials, researchers at Yale and Harvard universities have fundamentally changed an organism’s genome for the first time. The researchers developed a new genome for an e.coli bacterium by replacing one kind of codon — a sequence of three nucleotides that regulates amino acids — with another kind of codon. Scientists have previously replaced genes, but this is the first time that such changes have been across the an organism’s genome, the complex blueprint of life. By recoding the genome, researchers say, the bacteria will be able to produce proteins that don’t occur in nature, creating the possibility of new drugs and biotechnology materials.
