This interactive model allows the user to explore the structure of DNA in full 3D. This facilitates easy understanding of the helical spiral of the polymer strand, joined by a backbone of ester bonds, formed from the joining of sugar and phosphate groups. What can be an extremely hard concept to put across is made easier by the fact that users can familiarize themselves with the structure at their own pace and in their own way. This is only a sample of the content available.
