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 ...

This image depicts the chemical structure of cytosine. It shows a hexagonal ring with nitrogen atoms at positions 1 and 3, and a primary amine group attached to carbon 4. The two remaining positions ...

Chemical structure of guanine, showing its double-ring purine structure and the functional groups involved in hydrogen bonding with cytosine. (Image: Public Domain) Guanine has the chemical formula ...

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 ...

On the left are three forms of the same RNA molecule, which is stabilised into a single form (on the right) by mitoxantrone. Ribonucleic acids (RNAs) serve as messengers between DNA and protein ...

SANTA CRUZ, CA — Researchers at the University of California, Santa Cruz, have determined the three-dimensional structure of an RNA enzyme, or “ribozyme,” that carries out a fundamental reaction ...
