Question

39. What is responsible for the increased stability of DNA compared to RNA?

A. Double phosphate backbone and no 2' hydroxyl
B. Functional R-groups and deoxyribose backbones
C. Hydrogen bonds holding the R-groups to the ribose
D. Quaternary structure and primary nucleci acid sequence

Answer 1

The increased stability of DNA compared to RNA is due to its double phosphate backbone and absence of a 2' hydroxyl group.

Step-by-step explanation:

Responsible for the increased stability of DNA compared to RNA:

The double phosphate backbone and absence of a 2' hydroxyl group in DNA, as compared to RNA, makes DNA more stable. The phosphate groups in DNA create a strong backbone, while the absence of the 2' hydroxyl group reduces the susceptibility to hydrolysis. These factors contribute to the overall stability of DNA.

On the other hand, RNA has a single phosphate backbone and possesses a 2' hydroxyl group, which makes it less stable and prone to degradation.
