The primary difference between DNA and RNA is that the sugar ring's 2' carbon atom in DNA does not have a hydroxyl group. Because DNA lacks a hydroxyl group, which prevents it from being hydrolyzed, it is more stable than RNA. DNA has the letters A, T, G, and C, whereas RNA has the letters A, U, G, and C.
