Ribosomes

  1. 1. RIBOSOMES Lorena Latre Navarro 2º BTO A IES Lucas Mallada
  2. 2. RIBOSOMES INTRODUCTION <ul>Discovered by George Emil Palade (1953) </ul>Ribosome
  3. 3. WHERE? We can found ribosomes in the mitochondrial matrix too. Rough endoplasmic reticulum
  4. 4. PROKARYOTIC CELL EUKARYOTIC CELL
  5. 5. COMPOSITION <ul>Ribosomal RNA + fifty or more structural proteins = RIBOSOME </ul>
  6. 7. STRUCTURE <ul><li>Without MEMBRANE
  7. 8. Two SUBUNITS
  8. 9. Large subunit
  9. 10. Small subunit </li></ul>
  10. 12. Sedimentation's coefficent Ribosomal RNA Eukaryotic Prokaryotic Eukaryotic Prokaryotic LARGE SUBUNIT 60 S 50 S 32 S 28 S SMALL SUBUNIT 40 S 30 S 18 S 16 S SUBUNITS
  11. 13. FUNCTION <ul>PROTEIN BYOSINTHESIS <li>Transcription -> mRNA
  12. 14. tRNA's nucleobases join to mRNA's nucleobases
  13. 15. Translation by the ribosomes </li></ul>
