Study of ribosome evolution challenges 'RNA World' hypothesis

In the beginning – of the ribosome, the cell's protein-building workbench – there were ribonucleic acids, the molecules we call RNA that today perform a host of vital functions in cells. And according to a new analysis, ...

Biologists uncover a novel cellular proofreading mechanism

(PhysOrg.com) -- To make proteins, cells assemble long chains of amino acids, based on genetic instructions from DNA. That construction takes place in a tiny cellular structure called a ribosome, to which amino acids are ...

Detailed view of a crucial enzymatic complex revealed

Researchers led by ETH professor Nenad Ban have now completed the three-dimensional structure of the ribosome from a higher organism. This structure will increase the understanding of this cellular “protein factory” ...
