PROTEINS AND CELLS: NEWS

  1. 1. HOW CELLS EXPORT AND EMBED PROTEINS IN THE MEMBRANE …AND… SCIENTIST VIEW GENOME AS IT TURNS ON AND OFF INSIDE CELLS   ANA CRISTINA ALVARADO VELASQUEZ MEDICINE STUDENT
  2. 4. INTRODUCTION
  3. 5. SCIENTIST VIEW GENOME AS IT TURNS ON AND OFF INSIDE CELLS 1 <ul><li>Today, scientific advances enable to  see the transformation of DNA into RNA. </li></ul>
  4. 6. SCIENTIST VIEW GENOME AS IT TURNS ON AND OFF INSIDE CELLS 2 <ul><li>Doctors johnathan s. werssman and L. stirlyng churchnman supported the study of RNA. </li></ul>
  5. 7. SCIENTIST VIEW GENOME AS IT TURNS ON AND OFF INSIDE CELLS 3 <ul><li>Histones, nucleosomes are wrapped in key structures for the genome. </li></ul>
  6. 8. SCIENTIST VIEW GENOME AS IT TURNS ON AND OFF INSIDE CELLS 4 <ul><li>The enzyme polymerase, histones and the nucleosomes are very important for the study of DNA transcription. </li></ul>
  7. 9. PERSONAL OPINION <ul><li>This new approach gives researchers an insight into the process in action, as well as know ledge on general trends in the activation or deactivation of the genome.  </li></ul>
  8. 10. HOW CELL EXPORT SND EMBED PROTEINS IN THE MEMBRANE 1 <ul><li>The disorders in proteins may be a cause for diseases like Parkinson's. </li></ul>
  9. 11. HOW CELL EXPORT SND EMBED PROTEINS IN THE MEMBRANE 2 <ul><li>A factor of protein transport through the membrane is SRP (signal </li></ul><ul><li>  recognition particle) </li></ul>
  10. 12. HOW CELL EXPORT SND EMBED PROTEINS IN THE MEMBRANE 3 <ul><li>A ribosome-protein complex is a factor in protein transport. </li></ul>
  11. 13. HOW CELL EXPORT SND EMBED PROTEINS IN THE MEMBRANE 4 <ul><li>Cryo-electron microscopy (cryo-electronics) is a technique for imaging in the transport of proteins across the membrane </li></ul>
  12. 14. PERSONAL OPINION <ul><li>It is interesting to know that there are methods of microscopy which enable to do studies in living cells.  </li></ul>
  13. 15. MEDICAL UTILITY 1 <ul><li>It is unlikely to know a result of an experiment because they are hypotheses </li></ul>
  14. 16. MEDICAL UTILITY 2 <ul><li>Genetics are not experienced in humans because the outcome is  </li></ul><ul><li>uncertain. </li></ul>
  15. 17. MEDICAL UTILITY 3 <ul><li>The proteins are important structures and essential in the  </li></ul><ul><li>development of an organism </li></ul>
  16. 18. MEDICAL UTILITY 4 <ul><li>The study of genetics may be an option for the  </li></ul><ul><li>treatment of some diseases </li></ul>
  17. 19. BIBLIOGRAPHY <ul><li>Sciencedaily, Wow cell export and embed proteins in the membrane, January 3. 2011. </li></ul><ul><li>Sciencedaily, Scientists view genome as it turns on and off inside cell. January 20, 2011. </li></ul>
  18. 20. THANK YOU
