Differences between DNA and RNA
| DNA | RNA |
| Double stranded helix (anti-parallel) | Single stranded | Bases are G,C,A,T | Bases are G,C,A,U | Sugar is deoxyribose | Sugar is ribose | Replicates from self (semi-conservative). New strand grows from 5' to 3' | Transcribed from DNA template (anti-sense strand) |
