| Feature | DNA | RNA |
|---|---|---|
| Sugar | Deoxyribose ($C_5$, no OH at C-2) | Ribose ($C_5$, has OH at C-2) |
| Bases | A, T, G, C | A, U, G, C (Uracil replaces Thymine) |
| Strands | Double helix (two strands) | Single-stranded |
| Function | Genetic info storage | Protein synthesis |
| Stability | More stable | Less stable |
$$Key difference: Deoxyribose vs Ribose sugar; Thymine vs Uracil$$
