* DNA contains deoxyribose sugar.
* RNA contains ribose sugar.
This difference in the sugar molecule is crucial for the structure and function of each nucleic acid:
* Ribose has a hydroxyl group (-OH) attached to the 2' carbon, while deoxyribose has only a hydrogen atom (-H) at that position.
* This makes RNA more reactive and less stable than DNA, which is essential for its role in protein synthesis.
Here's a table summarizing other key differences:
| Feature | DNA | RNA |
|---|---|---|
| Sugar | Deoxyribose | Ribose |
| Bases | Adenine, guanine, cytosine, thymine | Adenine, guanine, cytosine, uracil |
| Structure | Double helix | Single strand (except for some viral RNA) |
| Function | Genetic blueprint, storing genetic information | Involved in protein synthesis, carrying genetic information from DNA to ribosomes |
