These chains come in a wide range of lengths. In humans a typical protein is about 400 amino acids long; some are a lot longer. Molecules of RNA, one of the two nucleic acids, can reach up to 100,000 ...

A new study from the Hebrew University of Jerusalem published in the Proceedings of the National Academy of Sciences sheds ...

Proteins are life’s molecular workhorses, doing everything from turning sunlight into food to fighting viruses. They are built from 20 different types of amino acid molecules, so even a small protein ...

WHEN ST JOHN THE EVANGELIST wrote of the Word becoming Flesh, he was drawing on ideas of reason and order derived from classical Greek philosophy. But he was also providing a succinct description of ...

Using nanopore DNA sequencing technology, researchers have managed to scan a single protein: by slowly moving a linearized protein through a tiny nanopore, one amino acid at the time, the researchers ...

Chemists say they have solved a crucial problem in a theory of life’s beginnings, by demonstrating that RNA molecules can link short chains of amino acids together. The findings, published on 11 May ...
