Practice question
Question
Which of the following is the most probable explanation for higher lability of RNA than DNA?
Explanation
RNA possesses a 2'-hydroxyl group on ribose that acts as internal nucleophile, facilitating intramolecular transesterification and backbone cleavage under alkaline conditions. DNA lacks this hydroxyl, making its phosphodiester bonds significantly more stable against hydrolysis.
