  1. Macromolecules Biology 122 Genes and Development

  2. Functional groupsin biological molecules

  3. Carbohydrates

  4. Polysaccharides

  5. Nucleic acids

  6. On the right is Friedrich Miescher’s laboratory, where DNA was discovered. On the left is the adjacent lab of Felix Hoppe-Seyler, one of the founders of Biochemistry. From The Scientist, Dec. 2008

  7. DNA • B form of DNA: DNA at the Macromolecular Museum

  8. Proteins

  9. Tab. 3.2

  10. Protein structure Primary structure of insulin

  11. Protein structure Tertiary structure

  12. Protein structure • Proteins with the same function from different organisms have almost the same tertiary structure.

  13. Homeodomain protein tree. Green = plants; Brown = fungi; Blue = animals

  14. Example proteins • T7 DNA polymerase[single subunit] • Ruv A Recombinase[quaternary structure]

  15. Lipids
