- - - - Adenine
      - Cytosine
      - Guanine
      - Uracil
- - - - phosphate group
      - nitrogenous organic base
      - Pentose sugar (deoxyribose)
    - - Double helix
      - Two polynucleotides joined by hydrogen bonds between complimentary bases
      - Phosphodiester backbone
      - Base pairs
        
        Adenine-Thymine (double bond)
        
        Guanine-Cytosine (triple bond)
    - - The phosphodiester backbone protects the more chemically reactive nitrogen
      - Hydrogen bonds form bridges between the phosphodiester uprights. A higher proportion of C-G pairings makes DNA more stable
