Compare DNA and RNA molecules
Similarities between DNA and RNA
- Both contain purines adenine and guanine and the pyrimidine base cytosine
- Both contain phosphate groups.
- They both have a basic sugar- phosphate backbone in their chains
- Both contain polynucleotide chains.
Differences between DNA and RNA
| DNA | RNA |
| · Double stranded structure.
· Found only in the nucleus. · The sugar molecule is deoxyribose. · Contains a pyrimidine base thymine · Giant molecules with very high molecular weight · Has hydrogen bonds in its structure |
· Single stranded structure
· Found in both nucleus and cytoplasm · Found both sugar molecular is ribose · Contains a pyrimidine base uracil · Short, small with low molecular weight · Has no hydrogen bonds in its structure |
