A
RNA is typically double-stranded.
B
RNA is more stable than DNA.

D
RNA contains the sugar ribose.
Verified step by step guidance
1
Understand the basic structure of RNA: RNA, or ribonucleic acid, is a nucleic acid similar to DNA but with some key differences.
Identify the sugar component: RNA contains the sugar ribose, whereas DNA contains the sugar deoxyribose. This is a fundamental difference between the two molecules.
Examine the strand structure: RNA is typically single-stranded, unlike DNA, which is double-stranded. This structural difference affects their functions and stability.
Consider the nitrogenous bases: RNA contains the bases adenine, guanine, cytosine, and uracil. In contrast, DNA contains thymine instead of uracil.
Evaluate stability: RNA is generally less stable than DNA due to the presence of the hydroxyl group on the ribose sugar, which makes it more prone to hydrolysis.
