Ribosomal RNA (rRNA) is a type of molecule and a key building block of the ribosome, the cell's protein-making machinery. rRNA accounts for much of the RNA in a cell, and it's crucial for life. It's ...

Ribosomal subunit assembly and biogenesis constitute a fundamental process vital for cellular protein synthesis across all domains of life. This complex, multi-step pathway involves the transcription ...

How does a cell know when it’s been damaged? A molecular alarm, set off by mutated RNA and colliding ribosomes, signals danger. When the sun shines on your skin, what does it hit? When it causes a ...

Christine Dunham is a leading expert on the ribosome—an elaborate macro-molecular machine that operates like a factory within ...

We’re celebrating 180 years of Scientific American. Explore our legacy of discovery and look ahead to the future. In 1957, just four years after Francis Crick and other scientists solved the riddle of ...
