Ribosomes

  • The ribosomes are the organelles that are not bound by any membrane. 
  • These are made up of ribosomal RNA (rRNA) and proteins. Hence, these are ribonucleoprotein particles. 
  • These may be found attached to the rough endoplasmic reticulum or may be present freely in the cytoplasm. 
  • Each ribosome is made up of two subunits - a large subunit and a small subunit. 
  • The ribosomes in eukaryotic cells are of 80S type while in prokaryotic cells they are of  70S types. 
  • The ‘S’ denotes the Svedberg unit for sedimentation rate that measures shape, size and density of the ribosomes.
  • The main function of the ribosome is to perform the translation of the mRNA to form the polypeptide chain.
