A
DNA is single-stranded, while RNA is double-stranded.
B
DNA contains deoxyribose sugar, while RNA contains ribose sugar.

Verified step by step guidance
1
Begin by understanding the basic structural differences between DNA and RNA. DNA is typically double-stranded, forming a double helix, while RNA is usually single-stranded.
Examine the sugar components of each molecule. DNA contains deoxyribose sugar, whereas RNA contains ribose sugar. This is a key difference in their chemical structure.
Consider the location of these molecules within a cell. DNA is primarily found in the nucleus, while RNA can be found in both the nucleus and the cytoplasm.
Look at the nitrogenous bases used by each molecule. DNA uses thymine as one of its bases, while RNA uses uracil instead of thymine.
Review these differences to identify the correct statement: DNA contains deoxyribose sugar, while RNA contains ribose sugar.
