In the double helix structure of DNA, thymine forms a base pair with adenine through two hydrogen bonds. This specific pairing is known as complementary base pairing and is essential for the stability ...

Erwin Chargaff's groundbreaking research, which showed that DNA base pairs had a complementary relationship, laid the foundation for James Watson's and Francis Crick's DNA model. When word spread that ...

Molecular models are a tried-and-tested tool for teaching chemistry to students of all ages. By enabling users to visualize the three-dimensional structure of a molecule and how its atoms are arranged ...

The idea of the genetic code was one of the most important and captivating implications of the discovery of the double-helical structure of DNA (Yanofsky, 2007). It has transpired that the genetic ...

We present a set of protocols showing how to use the 3DNA suite of programs to analyze, rebuild and visualize three-dimensional nucleic-acid structures. The software determines a wide range of ...

Miniature architectural forms -- some no larger than viruses -- have been constructed through a revolutionary technique known as DNA origami. Now, scientists have expanded the capability of this ...
