Multiple Choice
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.
Verified step by step guidance1
Identify the three tRNA binding sites on the ribosome: A-site, P-site, and E-site.
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.
Understand the function of the P-site: It holds the tRNA carrying the growing polypeptide chain.
Understand the function of the E-site: It is the exit site where the tRNA, now without an amino acid, exits the ribosome.
Evaluate the given options based on the functions of the A-site, P-site, and E-site to determine which statements are correct.
