Question

Eukaryotes possess which of the following type of ribosomes?

• A. 60 S
• B. 70 S
• C. 80 S
• D. Both B and C

Answer 1

The correct option is D Both B and C

• 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 eukaryotic cell, the ribosome present is an 80S type and the cellular organelles (mitochondria and chloroplasts) have 70S type
• It is made up of two subunits- a larger subunit 60S and a smaller subunit 40S.
• So, the correct answer is 'Both B and C'.
