A new study finds that at least one Archaea has surprisingly flexibility when interpreting genetic code, which goes against a ...

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 ...

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 ...

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 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 ...

To overcome the inherent challenge of translation termination interference caused by stop codon reprogramming in mammalian cells, researchers from Peking University led by Chen Peng from College of ...

The rise of antimicrobial-resistant pathogens has spurred scientists to search far and wide for new drugs. And while many antimicrobial molecules have been discovered in recent years, it’s rare to ...

Scripps Research scientists have developed a simpler method to add new amino acids to proteins using four-nucleotide codons, creating novel peptides with potential applications in drug discovery and ...

Stool samples can help doctors diagnose some health conditions. Tips for collecting a stool sample include urinating before collecting the sample and using any tools that the sample kit provides.
