Select One Factor That Contributes to the Higher Stability of DNA

Question

Select one factor that contributes to the higher stability of DNA compared to RNA
A) DNA has one hydroxyl group
B) DNA is single-stranded
C) Ribonucleases degrade DNA
D) DNA contains guanine

Accepted Answer

DNA has one less hydroxyl group than RNA, making it less susceptible to hydrolysis and thus more stable. RNA contains an additional hydroxyl group on the 2' carbon of its sugar (ribose), making it more reactive and less stable than DNA, which contains deoxyribose.
