The code of life is simple. Four genetic letters arranged in triplets—called codons—encode amino acids. These are the building blocks of proteins, the machinery that powers life. But the genetic code ...

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 ...

We’ve heard of GMOs, but this is ridiculous. Scientists at the Medical Research Council’s Laboratory of Molecular Biology say they’ve engineered a bacteria whose genetic code is more efficient than ...

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 have engineered a strain of bacteria with a genetic code unlike anything found in nature, marking a groundbreaking advance in synthetic biology. The microbe, called Syn57, is a lab-made ...
