Ribosomes Ribosomes Presentation Transcript

  • RIBOSOMES
  • RIBOSOMES INTRODUCTION
      Discovered by George Emil Palade (1953)
    Ribosome
  • WHERE? We can found ribosomes in the mitochondrial matrix too. Rough endoplasmic reticulum
  • PROKARYOTIC CELL EUKARYOTIC CELL
  • COMPOSITION
      Ribosomal RNA + fifty or more structural proteins = RIBOSOME
  •  
  • STRUCTURE
    • Without MEMBRANE
    • Two SUBUNITS
    • Large subunit
    • Small subunit
  •  
  • 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
  • FUNCTION
      PROTEIN BYOSINTHESIS
    • Transcription -> mRNA
    • tRNA's nucleobases join to mRNA's nucleobases
    • Translation by the ribosomes
