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 ...

Scientists profiling small non-coding RNAs in postmortem brain tissue from people with schizophrenia and bipolar disorder have identified sweeping molecular disruptions that extend well beyond the ...

Research identifies ribosome biogenesis factor MYBBP1A as a driver of acute myeloid leukaemia growth, highlighting a ...

The ribosome is a fundamental cellular machine responsible for protein synthesis. Its complex structure, comprising distinct functional centres such as the peptidyl transferase centre (PTC) and the ...

Proteins that trigger cell senescence occupy much of the literature on aging, but a small RNA moves into the limelight. Further investigation into SNORA13 revealed that it modifies RNA bases in the ...

Oceans churned with lava. Air filled thick with smoke. Asteroids stormed down incessantly. Life during the Hadean Eon four billion years ago was a struggle, and yet that was when it began. 1,2 With no ...

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 ...

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 ...
