Multiple Choice
Which of the following is a major difference between RNA and DNA?
A
RNA is double-stranded while DNA is single-stranded.
B
RNA contains uracil instead of thymine.
C
RNA has a deoxyribose sugar while DNA has a ribose sugar.
D
RNA is more stable than DNA under alkaline conditions.
Verified step by step guidance
1
Identify the structural components of RNA and DNA. RNA contains ribose sugar, while DNA contains deoxyribose sugar.
Examine the nitrogenous bases present in RNA and DNA. RNA contains uracil, whereas DNA contains thymine.
Consider the stability of RNA and DNA under different conditions. RNA is generally less stable than DNA under alkaline conditions due to the presence of the 2'-hydroxyl group in ribose.
Analyze the strand structure of RNA and DNA. RNA is typically single-stranded, while DNA is double-stranded.
Compare the key differences between RNA and DNA based on the above observations to determine the major difference.
