  • Q:

    RNA can be seen to degrade if left at room temperature for too long, while DNA does not have this issue. The major reason for this is that

     

    A

    The DNA backbone provides additional stability that the RNA backbone does not provide.

    B

    The replacement of thymine with uracil decreases the stability of the RNA molecule.

    C

    DNA is wound more tightly around itself in a different manner than RNA, providing it increased stability.

    D

    DNA is a more stable molecule than RNA
