The enzyme RNA polymerase (RNAP) carries out transcription, copying DNA into RNA. It's the first step in gene expression, and a process fundamental to all life. But the inner workings of this ...

Scientists provide fresh insights on the origins of life, presenting compelling evidence supporting the 'RNA World' hypothesis. The study unveils an RNA enzyme that can make accurate copies of other ...

According to the RNA world hypothesis, life began when RNA molecules evolved the ability to make more copies of themselves. Now we have discovered an RNA molecule that is almost capable of this – it ...

RNA modifications have emerged as a pivotal area of focus in molecular biology and precision medicine. Recent breakthroughs highlight the dynamic nature of ...

A molecule so small it could fit on a Post-it note of genetic code has just pulled off something scientists have chased for ...

For decades, circular RNA was treated as little more than molecular background noise — stable fragments that accumulated in ...
