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 ...

This image illustrates the chemical structures of the five main nucleobases found in DNA and RNA. The pyrimidines, thymine (DNA), uracil (RNA), and cytosine are shown on top while the purines, adenine ...

Researchers in China have developed a new method that allows them to insert long stretches of DNA into a genome. The process, named GRAND editing, is one of a handful of new systems aimed at using two ...
