Scientists shrink E.coli's genetic code to contain only 57 of 64 codons
By reducing E. Coli's genetic code from 64 to 57 codons, scientists have redesigned the organism. They created a synthetic genome by deleting seven codons and substituting them with other codons that serve the same function. They created the simplified organism Syn57 by dividing the 4 Mb genome into 38 sections and making over 101,000 precise changes.
