Why is RNA more prone than DNA to forming secondary structures?

Solution

DNA has limited catalytic ability because it lacks functional groups that can participate in catalysis and has a regular structure that is not conducive to forming shapes required for catalysis.RNA molecules can catalyze some reactions because they have exposed hydroxyl functional groups and can fold into shapes that then can function in catalysis.The increased stability of RNA duplexes allows for highly diverse secondary and tertiary structures.
