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 ...

Researchers discover a unique genetic code in Antarctic archaea that encodes a rare amino acid, potentially advancing protein ...

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 ...

How did horses become some of the greatest athletes in the animal kingdom? Researchers at Johns Hopkins Medicine may have found the answer, pinpointing a genetic mutation and evolutionary process that ...

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 ...

It's a dogma taught in every introductory biology class: Proteins are composed of combinations of 20 different amino acids, arranged into diverse sequences like words. But researchers trying to ...

Liquid culture flasks of bacteria grown in yellow broth covered with tinfoil on a shaker. Bacterial strains needed to be tested every step of the way to create the highly compressed genome. Credit: ...

Gianni Castiglione did not set out to study horses. The Vanderbilt University biologist and his colleagues were interested in how different animal species balance the need to produce energy with the ...
