DNA and RNA are the molecular blueprints of life, each with unique structures and roles. DNA’s double-helix stability makes it ideal for long-term genetic storage, while RNA’s versatility powers ...

RNA Timeline: A History in Hybridization and Structure Alexander Rich and David Davies discover the double-stranded RNA helix and show that polyribo U and polyribo A hybridize spontaneously.6 Ben Hall ...

The scientist who discovered hybridization and the "other" double helix describes what it meant to biology. By Alexander Rich Fifty-two years ago I was venturing to the basement of Cal Tech chemistry ...

Nucleic acids are complex biological molecules that store and transmit genetic information in all living organisms. They are essential for the survival and reproduction of life on Earth. The two main ...

In the CRISPR toolkit, Cas12a2 is like a Swiss Army Knife—one tool that can do multiple things. The nuclease performs RNA-guided, sequence-nonspecific degradation of single-stranded RNA, ...
