What is the difference in the primary structure of DNA and RNA?
Understand the Problem
The question is asking for the differences between the primary structures of DNA and RNA, specifically focusing on aspects like nucleotide composition, structure, and location within the cell.
Answer
DNA uses deoxyribose, RNA uses ribose.
The primary structural difference between DNA and RNA is the sugar component; DNA contains deoxyribose, whereas RNA contains ribose.
Answer for screen readers
The primary structural difference between DNA and RNA is the sugar component; DNA contains deoxyribose, whereas RNA contains ribose.
More Information
The difference in sugar molecules is fundamental because the extra hydroxyl group in ribose makes RNA more reactive and less stable than DNA, which is crucial for its role in the cell.
Tips
A common mistake is confusing the sugars due to their similar names. Remember: deoxyribose lacks one oxygen atom compared to ribose.
