A ribosome has three tRNA binding sites. Which answer matches the tRNA binding site with the correct function:

• A. The A-site acts as the loading site, holding the tRNA with the next amino acid in the polypeptide sequence.
• B. The E-site releases charged tRNA from the ribosome.
• C. The P-site is holding the growing strand of amino acids making up the polypeptide.
• D. A and B are correct.
• E. B and C are correct.
• F. A and C are correct.
• G. All of the above are correct.

Answer: (F)

Verified step by step guidance

1. Identify the three tRNA binding sites on the ribosome: A-site, P-site, and E-site.
2. Understand the function of the A-site: It is the acceptor site where the tRNA carrying the next amino acid to be added to the polypeptide chain binds.
3. Understand the function of the P-site: It holds the tRNA carrying the growing polypeptide chain.
4. Understand the function of the E-site: It is the exit site where the tRNA, now without an amino acid, exits the ribosome.
5. Evaluate the given options based on the functions of the A-site, P-site, and E-site to determine which statements are correct.
