Somewhere in a sample of ordinary pond water, a single-celled organism has been quietly breaking one of biology’s most ...

Rule-breaking discovery: A freshwater ciliate uses stop codons to build amino acids instead of ending proteins, defying the 'universal' genetic code. Genetic code flexibility: The organism reassigns ...

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 ...

Human genes are written in long strings of three-letter units composed of four different nucleotides. These units—or codons—specify one of many amino acids, the building blocks of proteins. Multiple ...

How does the cell convert DNA into working proteins? The process of translation can be seen as the decoding of instructions for making proteins, involving mRNA in transcription as well as tRNA. But ...
