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 DNA and RNA are very similar. They are both ordered sequences of 4 types of substances: ACGT for DNA, and ACGU for RNA. Thus RNA uses the same three ACG substances, but uses U (uracil) instead of T (thymine). The molecules uracil and thymine are only slightly different chemically.
