Question

Which of the classes of RNA molecules carries the amino acids that are added to the growing polypeptide chain?

• A. Ribosomal RNA
• B. Transfer RNA
• C. Messenger RNA
• D. Primary mRNA transcript

Answer 1

The correct option is B Transfer RNA

Translation is the formation of proteins from the mRNA. Due to the continuous formation of proteins, a large chain of protein molecules is formed. This chain of protein molecules in a linear fashion is called a polypeptide chain and made up of amino acids. The tRNA (Transfer RNA) acts as the transporter of amino acids, They are clove-like structure and are folded to form a three-dimensional structure. These tRNA molecules help in carrying the amino acids to the polypeptide chain during translation.

So, the correct option is 'Transfer RNA'.
