  • DNA
    • Nucleotides
      • nitrogenous base
      • phosphate group
        • always the same
        • condensation reaction
      • sugar molecule (five carbon sugar)
        • condensation reaction
      • Lots bonded together=nucleic acids
    • Deoxyribonucleicacid
    • Sugar is deoxyribose
  • phosphate group
    • always the same
  • nitrogenous base
  • sugar molecule (five carbon sugar)
    • Covalent bonds
      • One single nucleotide molecule
        • Bonded to form chains
          • The 'backbone' of the molecule
