Genetic coding revamp

Published on

“Scientists have developed a new genetic language using a ribosome that can read instructions that are 4 base pairs long, enabling the construction of designer proteins containing a variety of unnatural elements, according to a study published online today (February 14) in Nature… synthetic biologist Jason Chin of the Medical Research Council Laboratory of Molecular Biology in Cambridge, UK, and his colleagues decided to devise a system that could read codons that are 4 base pairs long. Such a system could “open the door to what will be [the] truly revolutionary possibility [of creating] genetically coded polymers comprised of up to 256 [unique] building blocks.” More…
