Tutorial on DNA Structure - Three basepairs

Three base pairs

To view the DNA molecule on the left you require the Chemscape Chime plug-in with NetScape or Microsoft® Internet Explorer (requires Chime 2.0). If you can see the DNA molecule then you are ready to view the tutorial. The plug-in can be downloaded from MDL Information Systems, Inc.

Three base pairs are shown in stick form to highlight the bonds with the van der Waals radius shown as dots. You should be able to see that each base pair is related by 36^o.

To highlight different parts of the base pairs click one of the following options:
Reset
Show bonds and van der Waals radii (each bp is coloured differently)
Phosphates
Deoxyribose
Bases

To manipulate the model press and hold the left hand mouse button and drag to obtain the desired view. To alter the presentation of the image or stop the rotation click with the right hand mouse button and select one of the options.
