The genetics of a marine protozoan may overturn one of the long-held tenets of protein synthesis. According to conventional wisdom, the genetic code is unambiguous: each DNA triplet, or codon, ...

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

61 codons specify one of the 20 amino acids that make up proteins 3 codons are stop codons, which signal the termination of protein synthesis Importantly, the genetic code is nearly universal, shared ...

This is a summary of: Liu. H. et al. Viral RNA blocks circularization to evade host codon usage control. Nature https://doi.org/10.1038/s41586-025-09809-y (2025).

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 ...

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 ...

Scientists at deCODE genetics, a subsidiary of Amgen, have published a study in Nature Communications, comparing over 110 thousand patients with autoimmune thyroid disease (AITD) from Iceland, Finland ...

For decades, biology has relied on one central assumption: the genetic code is precise. DNA is transcribed into RNA, RNA is ...

Scientists discovered that aging DNA repeats expand at wildly different speeds—and in some people, the consequences can be devastating. A sweeping genetic study drawing on data from more than 900,000 ...

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 ...
