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 ...

For decades, biology students have learned one rule about the genetic code that supposedly has no exceptions: three specific DNA sequences act as stop signs, telling the cell’s protein-building ...

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 ...

Scientists testing a new method of sequencing single cells have unexpectedly changed our understanding of the rules of genetics. The genome of a protist has revealed a seemingly unique divergence in ...

The highly conserved CCA end sequence of tRNAs has been shown to be less critical than expected, enabling a more tunable ...

The genetic building blocks of life—formed from the four nucleotides adenine (A), cytosine (C), guanine (G), and thymine (T)—are read in groups of three known as codons. While some codons (known as ...

Living organisms synthesize a staggering variety of proteins by combining 20 amino acids into chains of any length and order. In the past, to expand protein diversity beyond the scope of these 20 ...

Genetic code expansion harnesses engineered translation machinery to incorporate noncanonical amino acids into proteins at designated sites, thereby reprogramming the chemical language of living cells ...

The Nature Index 2026 Research Leaders reveal the leading institutions and countries/territories in the natural sciences, health sciences, applied sciences and social sciences, according to their ...
