To understand what an individual RNA molecule does, its 3D structure needs to be deciphered at the level of its constituent atoms and molecular bonds. Researchers have routinely studied DNA and ...

The nucleotides are connected through phosphodiester bonds, forming a long chain. In DNA, two complementary strands of nucleotides pair up through hydrogen bonds between the bases (A with T and G with ...

The folded structures of biological molecules, from DNA to RNA and proteins, determine their biological action. Without structure there is no function, and without function there is no life.

Ribonucleic acid (RNA) molecules may be best known for their job ferrying the genetic information encoded in DNA to a cell's protein factories, but these molecules aren't just a middleman for ...

Ben Hall and Sol Speigelman carry out DNA-RNA hybridization in viral infected bacterial system. 15 Rich and colleagues publish on two RNA double helix fragments solving the structure at atomic ...

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 ...

What made ribose the sugar of choice for life's code? Scientists at Scripps Research may have cracked a major part of this mystery. Their experiments show that ribose binds more readily and ...

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 ...

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 ...
