Abstract

The recoded bacterium uses only 57 of the 64 possible genetic codes, freeing up seven to be used for different purposes We have gone further than ever before in creating life that is unlike anything that has evolved naturally. The genome of an Escherichia coli bacterium has been redesigned on a computer to use just 57 of the 64 genetic codes, which were synthesised from scratch and then put into a living bacterium.
