The "Dickerson Dodecamer" is shown using the Ball & Stick display. The 5' and 3' ends of each chain are labeled.
View an A-T or G-C base pair: An A-T base pair (distance in Å between C1' carbons). Remove distances. Number the adenine and thymine ring positions. A G-C base pair (distance in Å between C1' carbons). Number the guanine and cytosine ring positions. A G-C base pair (dot surface) above an A-T base pair (Spacefill). Place any of the above base pairs in the original double helix. Viewing tips: Use the buttons to the right of the image to show only portions of the structure; then use the Chime menu to display or color the molecule. The rotate buttons act on the entire structure. Remove the distance monitors with a second click. On this and other pages that display DNA structures, the nucleotides can be identified by choosing Shapely under the Chime Colors menu. The Shapely colors for DNA are:
