Apart from carrying the information to encode proteins in, RNA molecules can adopt intricate 2D and 3D structures. Specifically, the same RNA molecule can switch between ON and OFF structures, ...

What made ribose the sugar of choice for life's code? Scientists at Scripps Research may have cracked a major part of this ...

The nucleolus is where ribosomal RNA (rRNA) is transcribed, processed, and assembled into the building blocks of ribosomes, the molecular machines that make proteins. Researchers discovered that rRNA ...

In living organisms today, complex molecules like RNA and DNA are constructed with the help of enzymes. So how did these molecules form before life (and enzymes) existed? Why did some molecules end up ...

Losing a tooth as an adult is par for the course for many of us. The only option to replace them? Artificial substitutes. But ...

A new study provides a detailed structure of a human enzyme critical for antiviral defense and platelet function.
