Backbone representations are simplified 3D depictions of proteins or nucleic acids that enable the polymer chain structure to be seen. In proteins, a simple <font style="background:black;color:yellow;">&nbsp;backbone trace&nbsp;</font> connects alpha carbons ('''balls''') but the <font style="background:black;color:yellow;">&nbsp;backbone trace line&nbsp;</font> does not coincide with any of the covalent bonds in the main chain (<scene name='59/599354/Helix/13'>restore initial scene</scene>).

Perhaps the most common backbone representation is the <scene name='59/599354/Helix/10'>ribbon</scene>. Here the <font style="color:#ff0080;">&nbsp;ribbon is violet&nbsp;</font>, the [[DRuMS#Element|standard secondary structure color]] for alpha helices. As you can see, the ribbon is a smoothed backbone trace expanded in width. The''' arrowhead''' at one end points to the carboxyl terminus.
