In Biology 101, we learn that RNA is a single, ribbon-like strand of base pairs that is copied from our DNA and then read like a recipe to build a protein. But there's more to the story. Some RNA ...

Scientists have been unable to determine the structure of a biologically important so-called GAG proteoglycan -- or even to agree whether these remarkably complex molecules have well-defined ...

Many bacteria and archaea contain clustered regularly interspaced short palindromic repeats (CRISPRs) that confer resistance to invasive genetic elements. Central to this immune system is the ...

A scientist has used a form of artificial intelligence known as deep learning to predict the 3D structure of effectively any protein based on its amino acid sequence. This new approach for ...

G-quadruplexes (G4s) are non-canonical nucleic acid structures formed by guanine-rich DNA sequences and stabilized by Hoogsteen hydrogen bonds and monovalent cations. These structures are biologically ...
