A simple mechanical model to effectively implement the well-known double-stranded structure and the elasticity of DNA on a nano-meter scale has been developed by Jae-Hyung Jeon and Wokyung Sung of ...

James Watson’s discovery of DNA’s structure, the double helix, with Francis Crick in 1953, revolutionized human understanding of how life works, but other pioneering scientists paved the way for their ...

Billions of years ago, when the Earth was in its infancy and biology hadn't even gotten going, the precursors to the first living organisms were probably self-replicating strands of RNA. Scientists ...

The research duo also showed analytically how a wormlike-chainlike elastic model, frequently used in DNA mechanics, can be derived by using their new model. It is used to explain the bending and twist ...
