  • 7. What is Life?: Dictionary.com Unabridged (v 1.1) - Cite This Source - Share This life       laɪf/ Pronunciation Key - Show Spelled Pronunciation [lahyf] Pronunciation Key - Show IPA Pronunciation noun, plural lives       laɪvz/ Pronunciation Key - Show Spelled Pronunciation [lahyvz] Pronunciation Key - Show IPA Pronunciation , adjective – noun 1.the condition that distinguishes organisms from inorganic objects and dead organisms, being manifested by growth through metabolism, reproduction, and the power of adaptation to environment through changes originating internally. 2.the sum of the distinguishing phenomena of organisms, esp. metabolism, growth, reproduction, and adaptation to environment.

  • 12. Take Home I <ul><ul><ul><li>What is Life? </li></ul></ul></ul>Terrestrial living systems are all based on carbon compounds and use liquid water. They are self-contained, use macromolecules such as nucleic acids and proteins to function, and react to and adapt to their environment over the short-term (movement) and also over the long-term (evolution).
  • 13. The Basic Unit of Life on Earth is the Cell-and there are Two Types: Prokaryote Eukaryote plant animal
  • 14. Prokaryotic Cell Structure Prokaryote=no nucleus
  • 15. Eukaryotic Animal Cell Structure Eukaryote=has a nucleus
  • 16. Eukaryotic Plant Cell Structure
  • 17. http:// www.youtube.com/watch?v =MMrvmZ2i1sE The “Inner Life” of a Eukaryotic Cell
  • 18. http:// www.youtube.com/watch?v =MMrvmZ2i1sE The “Inner Life” of a Eukaryotic Cell
  • 19. Size-Eukaryotes are Generally Bigger than Prokaryotes
  • 20. Prokaryotes & Eukaryotes have Different Genetic Structures as Well…
  • 21. Take Home II <ul><ul><ul><li>The Cell is the Basic Unit of Life on Earth </li></ul></ul></ul>There are two types of cells, prokaryotes and eukaryotes, each of which have very different structures, genetic mechanisms and behaviors yet are composed of mostly the same kinds of biomolecules and have very similar genetic codes…
  • 22. from Doolittle, W. Ford (1997) Proc. Natl. Acad. Sci. USA 94, 12751-12753 The Tree of Life:
  • 23. <ul><li>Most of modern cell and molecular biology has been </li></ul><ul><li>derived from the study of about 8 “model” organisms: </li></ul><ul><ul><li>E. coli </li></ul></ul><ul><ul><li>Yeast </li></ul></ul><ul><ul><li>C. elegans (nematode) </li></ul></ul><ul><ul><li>Drosophila (Fruit Fly) </li></ul></ul><ul><ul><li>Arabidopsis (plant) </li></ul></ul><ul><ul><li>Mouse </li></ul></ul><ul><ul><li>Rat </li></ul></ul><ul><ul><li>Human </li></ul></ul><ul><li>Based on the principle of conservation through evolution, </li></ul><ul><li>the lessons learned from these “models” are assumed to </li></ul><ul><li>be applicable to all terrestrial cells and organisms…there </li></ul><ul><li>are exceptions however…more on this later…much later… </li></ul>Model Organisms:
  • 24. Take Home III <ul><ul><ul><li>All Life on Earth is Related via a Common Ancestor </li></ul></ul></ul>All organisms on earth are related by evolution from a common ancestor which existed on Earth about 4-3.5 billion years ago…this fact allows us to use studies of a few “Model” organisms to form the basis for our understanding of all Life…
  • 25. The “Central Dogma” of Molecular Biology: DNA RNA PROTEIN START STOP TRANSCRIPTION TRANSLATION REPLICATION GENE CODONS AMINO ACIDS
  • 26. The “Central Dogma” in Action: http:// www.youtube.com/watch?v = NJxobgkPEAo
  • 27. The “Central Dogma” in Action: http:// www.youtube.com/watch?v = NJxobgkPEAo
  • 28. Molecular Biology's Central Dogma- The Movie! (everything to scale)! http:// www.youtube.com/watch?v =GkdRdik73kU
  • 29. Molecular Biology's Central Dogma- The Movie! (everything to scale)! http:// www.youtube.com/watch?v =GkdRdik73kU
  • 30. Take Home IV <ul><ul><ul><li>The “Central Dogma” of Molecular Biology </li></ul></ul></ul>All known Earth organisms use DNA, RNA and Proteins. These “parts” function according to the so called “Central Dogma” of Molecular Biology… DNA>RNA>PROTEIN
  • 31. Proteins act as Enzymes: http:// www.youtube.com/watch?v = cbZsXjgPDLQ
  • 32. Proteins act as Enzymes: http:// www.youtube.com/watch?v = cbZsXjgPDLQ
  • 33. Proteins act as Machines: http:// www.youtube.com/watch?v =InIha7bCTjM&feature=related
  • 34. Proteins act as Machines: http:// www.youtube.com/watch?v =InIha7bCTjM&feature=related
  • 35. Take Home V <ul><ul><ul><li>All Life can be Understood in Chemical Terms </li></ul></ul></ul>All known Earth organisms use proteins to accomplish such basic functions as metabolism and movement, and as such all biological activity can be understood in chemical terms
  • 36. Next Week: Biomolecules, Viruses and Cells More details on the chemicals and molecules that make up cells and viruses…what they look like and how they work…
  • 37. Instructor Mark E Minie PhD [email_address]
