The DNA of nearly all life on Earth contains many redundancies, and scientists have long wondered whether these redundancies served a purpose or if they were just leftovers from evolutionary processes ...

Synthetic biologists from Yale were able to re-write the genetic code of an organism - a novel genomically recoded organism (GRO) with one stop codon - using a cellular platform that they developed ...

The genetic code is the recipe for life, and provides the instructions for how to make proteins, generally using just 20 amino acids. But certain groups of microbes have an expanded genetic code, in ...

Most organisms on Earth have the same basic genetic code, but it comes with some flaws. Scientists sought to work out those errors by creating their own artificial genome, which replaced E. coli’s ...

Scientists trying to engineer biologic molecules with new functions have long felt limited by the 20 amino-acid building blocks. Researchers are working to develop ways of putting new building ...
