Question

Ribosomes of eukaryotes are different from those of bacterial cells in having

• A. Smaller size (70 S type)
• B. Larger size (80 S type)
• C. Differential chemical structure
• D. All of the above

Answer 1

The correct option is B Larger size (80 S type)

• Ribosomes of eukaryotes are different from those of bacterial cells in having a larger size.
  
• Ribosomes are known as protein factories because they are the main site of protein synthesis.
  
• It is made up of two subunits-
• Large subunits- join amino acids to form a polypeptide chain.
• Small subunits- reads RNA.
• In a prokaryotic cell, the ribosome is 70S type whereas, in a eukaryotic cell it is an 80S type.
• So, the correct answer is 'Larger size (80 S type)'.
