Solution
Correct Answer:
Ribose sugar and uracil instead of thymine
There are three primary differences between RNA and DNA:
- Sugar: RNA contains D-Ribose (−OH at C2), while DNA contains 2-Deoxy-D-ribose (−H at C2).
- Bases: Both have Adenine, Guanine, and Cytosine. However, RNA has Uracil (U) whereas DNA has Thymine (T).
- Structure: RNA is generally single-stranded, whereas DNA exists as a double helix.
This easy difficulty chemistry question is from the chapter biomolecules, covering the topic of nucleic acids. It appeared in the 2025 exam.
