This representation is a general overview of the molecule and highlights the important aspects of secondary structure. The helices, sheets and loops are all assigned a cartoon representation and are colored; helices in red, sheets in yellow and loops in cyan. If DNA and/or RNA are present in the molecule, they are colored using the CPK color scheme. To differentiate between the two, DNA is shown using sticks while RNA takes on a ball and stick representation. Finally, any ligands present are set to display as spheres and are colored cyan.
