    • RNA is made up of ribose sugar (plz see the attachment for its structure )
    • Whereas , DNA is made up of de oxy ribose sugar. (please see the attachment for its structure)
    • Due to the presence of –OH group in the ribose sugar, it is more active.
    •  
    • Also, the nitrogenous base is hydrophobic whereas the sugar end and the phosphoric acid end present in both RNA & DNA is hydrophilic.
    •  
    • Nitrogenous base always wants to stay away from the universal solvent.


    Since DNA is double stranded, it has its nitrogenous base in the interior of both the strands , thus keeping it away from water.

    But RNA is single stranded, hence its nitrogenous base is not away from water, and thus is reactive.
