Q. Refer to the given diagram of ribose sugar found in RNA

Which among the following group makes RNA easily degradable and labile?

A) A only
B) B and C
C) B only
D) A and D
Explanation

RNA is easily degradable and labile due to the presence of highly reactive 2’- OH group in its nucleotides containing ribose sugar. This 2’ OH group is not present in deoxyribose sugar found in the nucleotides of DNA. Thus, DNA is more stable than RNA. [image:6_image87.emf]
