Which of the following is not a major difference between DNA and RNA?
A
DNA and RNA both have the same phosphate backbone.
B
DNA is double-stranded, whereas RNA is typically single-stranded.
C
DNA uses thymine as a base, while RNA uses uracil.
D
DNA contains deoxyribose sugar, while RNA contains ribose sugar.
Verified step by step guidance1
Identify the structural components of DNA and RNA, focusing on the sugar and phosphate backbone.
Understand the base pairing differences between DNA and RNA, specifically thymine in DNA and uracil in RNA.
Recognize the typical structural form of DNA as double-stranded and RNA as single-stranded.
Examine the sugar molecules present in DNA and RNA, noting that DNA contains deoxyribose and RNA contains ribose.
Determine which statement does not describe a major difference between DNA and RNA by comparing the phosphate backbone, which is common to both.
