  The uprights are called the backbone and is made up of ribose (a pentose sugar) and phosphate. The rungs are the bases that are the actual coding bit of DNA. These are c â¦ arbon and nitrogen-based molecules that attach to the backbone.he rungs are made up of four nitrogen bases called Guanine, Thymine, Adenine, and Cytosine.
