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 ...

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 ...

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 ...

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 ...

Google DeepMind has expanded its AlphaFold AI system to not only predict the structure of proteins, but also to model how proteins interact with other cell structures, including DNA, RNA, and small ...

Within each cell, there is a constant struggle between life-sustaining molecules and molecules that could hasten its demise.

RNAs play an integral part in all kingdoms of life and mediate critical processes from gene regulation to genomic maintenance and protein synthesis. RNAs also have an amazing diversity in structure ...
