A phosphate backbone attaching double bones to oxygen and single bonds to hydroxy, with a hydroxy tail on one end. On the other end a similar hydroxy group is attached, but upon that nitrogen groups attach to that. These nitrogen groups contain pentagon shapes and have both double and single bonds (1 on the first nitrogen group and the second being entirely double bonded.) Lastly attaching to the double bonded nitrogen group is a NH2.
