  • Amino acids vs nucleic acids
    • Both contain the elements CHON 
    • Both can link to form larger molecules- polymers from individual monomers 
    • Nucleotides
      • Nucleotides consist of nitrogenous base 
        • plus pentose and phosphate 
      • bases are pyrimidines and purines 
      • Five different bases in nucleotides
        • By hydrogen bonds 
        • Adenine with thymine or uracil and guanine with cytosine 
        • Bases can undergo complementary base pairing 
        • Nucleotides carry genetic information 
    • Amino acids
      • Amino acids possess an amine, NH2 group and carboxylic group 
      • Variable R group 
      • More than 20 types of amino acid 
      • Amino acids link together by peptide bond formation-sugar phosphate backbone 
    • Sulphur containing vs. phosphate containing.
