- DNA & RNA are both polynucleotides.
- The basic structure of a nucleotide is:
DNA | RNA | |
Number of Strands | Two antiparallel strands | One strand |
Length | Very long | Relatively short |
Pentose Sugar | Deoxyribose | Ribose |
Nitrogenous Bases | Adenine, Cytosine, Guanine & Thymine | Adenine, Cytosine, Guanine & Uracil |
Function | Store genetic information | Transfer genetic information & forms ribosomes with proteins |
