A tiny chemical difference makes RNA better than DNA at forming liquid-like droplets under high temperatures and acidic ...

For decades, the central dogma of molecular biology—DNA makes RNA, RNA makes protein, protein makes phenotype—was the guiding framework for understanding inheritance and disease. This model explained ...

Although there are striking differences between the cells that make up your eyes, kidneys, brain and toes, the DNA blueprint for these cells is essentially the same. Where do those differences come ...

A molecular illustration of the crowded interior and cell envelope of Escherichia coli. (David S. Goodsell, The Scripps ...

Nevertheless, some preliminary steps have been taken. Researchers have managed to add some new amino acids to a bacterial ...

The original version of this story appeared in Quanta Magazine. For a molecule of RNA, the world is a dangerous place. Unlike DNA, which can persist for millions of years in its remarkably stable, ...

It's one of the origins of life's chicken-or-the-egg problems: How could RNA have helped give rise to the first cells before there ...

Ribosomal RNA (rRNA), made from many copies of ribosomal DNA (rDNA), is the core component that powers ribosomes—protein-building machines in our body. It helps build proteins by linking amino acids ...
