Which of the following is a characteristic feature of DNA, but not RNA?
Understand the Problem
The question asks to identify a characteristic unique to DNA and not found in RNA. This requires understanding the structural differences between the two nucleic acids, focusing on their nitrogenous bases, sugar components, and overall structure.
Answer
DNA contains deoxyribose and thymine, whereas RNA contains ribose and uracil.
DNA contains thymine, while RNA contains uracil. Furthermore, DNA contains deoxyribose, while RNA contains ribose.
Answer for screen readers
DNA contains thymine, while RNA contains uracil. Furthermore, DNA contains deoxyribose, while RNA contains ribose.
More Information
The key structural differences between DNA and RNA lie in their sugar composition (deoxyribose vs. ribose) and one of their nucleobases (thymine vs. uracil). These differences contribute to their distinct roles and stability within the cell.
Tips
A common mistake is to confuse the sugar and base differences between DNA and RNA. Remembering that DNA has deoxyribose and thymine can help distinguish it from RNA, which has ribose and uracil.
