Bases and sugar[edit] DNA is a long polymer with deoxyriboses and phosphate backbone. Having four different nitrogenous bases: adenine, guanine, cytosine and thymine. RNA is a polymer with a ribose and phosphate backbone. Four different nitrogenous bases: adenine, guanine, cytosine, and uracil. Structure of ribose in RNA Structure of deoxyribose in DNA.
The structure of RNA differs fundamentally from that of DNA in three ways: 1  It forms a single strand sugar-phosphate chain. 2  The sugar in its nucleotides is ribose. 3  The base thymine is replaced by the base uracil.
