Intracellular machines called ribosomes use messenger-RNA sequences to synthesize proteins. Investigations using single-molecule imaging and cryo-electron microscopy techniques reveal structural and ...

Christine Dunham is a leading expert on the ribosome—an elaborate macro-molecular machine that operates like a factory within a cell to manufacture proteins. "The ribosome is really the most ...

Scientists have discovered that some tiny segments of RNA thought to be junk instead have a functional role in suppressing production of certain messenger RNAs and appear to help cells respond to ...

RNA is one of the bodies most vital molecules, and it comes in a few forms. For example, messenger RNA fills an essential role in gene expression by copying the sequences of active genes, which are ...

A forested hill and clouds are in the background of an image of a shallow pool of steaming water, with the ground underneath colored in shades of beige, red, and brown. Life may have first emerged in ...

To build proteins, cells rely on a molecule called transfer RNA, or tRNA. tRNAs act like protein-building couriers, where they read the genetic instructions from messenger RNA, mRNA, and deliver the ...
