View molecules

To go into the viewing mode, you need to select the corresponding item in the Display menu. Here you will find such options as wireframe, backbone, spacefill, ribbons, strands and cartoons, as well as molecular surface. Thanks to the Color menu you can emphasize the different parts of a molecule by highlighting them manually.
