2/9/11 Ribosomes Presentation

  1. 1. RIBOSOMES<br />THE BEST ORGANELLE EVER<br />
  2. 2. <ul><li>Protein Builders+ Synthesizers
  3. 3. Read the RNA’s information and use it to create proteins (translation)</li></ul>WHAT DO THEY DO?<br />
  4. 4. <ul><li>5-10 nm larger in eukaryotic cells
  5. 5. Made out of complexes of RNAs and proteins
  6. 6. 2 subunits:
  7. 7. smaller attaches to mRNA
  8. 8. Larger binds to the tRNA and amino acids
  9. 9. Then they split</li></ul>WHAT DO THEY LOOK LIKE?<br />
  10. 10. <ul><li>Prokaryotes: free forms in cytoplasm and protoplasm
  11. 11. Eukaryotes:
  12. 12. free in cytoplasm for use inside cell
  13. 13. attached to outer membrane of endoplasmic reticulum for use outside of cell</li></ul>WHERE DO THEY LIVE?<br />
  14. 14. PLANT AND ANIMAL CELLS<br />PLANT <br />ANIMAL<br />
  15. 15. WHAT HAPPENS WHEN THEY DON’t work right?<br /><ul><li>Diamond-BlackfanAnemia
  16. 16. 5 infants/million
  17. 17. Heart and skeletal abnormalities, not enough red blood cells
  18. 18. The 7 mutated genes give faulty instructions on how to make ribosomal proteins
  19. 19. Cartilage Hair Hypoplasia
  20. 20. Relatively rare, but 1/19 of the Amish population are carriers
  21. 21. Anemic, short limbs, leukopenia (low white blood cell count) and thrombocytopenia (low platelet count)
  22. 22. The gene mutation causes a buildup of one enzyme which builds ribosomal RNA
  23. 23. Shwachman-Diamond Syndrome
  24. 24. 1/100,000 children
  25. 25. Neutropenia (low white blood cell count) and Pancreatic problems that lead to steatorrhea (fatty bowel movement) because there aren’t enough enzymes to digest fats, anemia
  26. 26. The gene mutation is causing a low amount of enzymes made out of proteins
  27. 27. Dyskeratosis Congenita
  28. 28. 1/million children
  29. 29. Hair, nail, skin, lungs, blood, digestive and immune system abnormalities, aplastic anemia (bone marrow doesn’t make enough platelets, red or white blood cells),
  30. 30. Caused by gene mutation that causes ribosome deficiency</li></li></ul><li>PHOTO CREDITS<br />Slide 2: http://biology.about.com/b/2008/11/29/what-are-ribosomes.htm<br />Slide 3: http://barrett-group.mcgill.ca/teaching/nanotechnology/ribosome.jpg<br />Slide 4:http://web.jjay.cuny.edu/~acarpi/NSC/images/cell.gif<br />Slide 6:http://illnessesanimalsplants.wikispaces.com/file/view/plantcell.jpg/31816717/plantcell.jpg<br />http://images.protopage.com/view/721661/caa3z4ysta5s87lr2asekq5ng.jpg<br />
