  • Polynucleotides
    • DNA
      • double helix
      • two long chains of nucleotide molecules
        • linked together
        • Each chain is called a polynucleotide
        • Phosphate group
        • Five-carbon sugar, deoxyribose
        • an organic base
          • Purine bases: A and G
            • Contain 2 rings in their structure
          • Pyrimidine bases: T and C
            • contain 1 ring in structure
      • the chains are anti-parallel
      • join together by hydrogen bonds
    • A links with T C links with G
      • complementary base pairing
