The correct answer is option 4 i.e 20.

  • Proteins are the end products of the decoding process that starts with the information in the cellular DNA. 
  • Proteins are formed by the translation process which includes decoding of the genes on DNA to proteins.
  • This process involves 20 amino acids.
  • Each amino acid has unique side chains. The side chains of the amino acids have different chemistries.
  • These amino acids join together to form a polypeptide chain which further forms proteins.
