Figure 1.9The chemical differences between DNA and RNA

(A) RNA contains ribonucleotides, in which the sugar is ribose rather than 2′-deoxyribose. The difference is that a hydroxyl group rather than hydrogen atom is attached to the 2′-carbon. (B) RNA contains the pyrimidine called uracil instead of thymine.
