Question
Which of the following is TRUE of the tRNA binding sites of the ribosome and most importantly explain why you chose this answer?
The E site stands for the "entry" site.
The P site stands for the "polypeptide channel site."
The A site stands for the "active site."
The active site is located between the E and P sites.
The A site is closer to the 3' end of the mRNA molecule being translated than the P site.

Explanation / Answer
Answer:
The A site is closer to the 3' end of the mRNA molecule being translated than the P site.
Explanation:
The three tRNA sites are labeled A, P and E.
The P site, called the peptidyl site, binds to the tRNA holding the growing polypeptide chain of amino acids.
The A site (acceptor site), binds to the aminoacyl tRNA, which holds the new amino acid to be added to the polypeptide chain. The E site (exit site), serves as a threshold, the final transitory step before a tRNA now bereft of its amino acid is let go by the ribosome.
The A site is closer to the 3' end of the mRNA molecule being translated than the P site. The P site is closer to the 5' end of the mRNA molecule. The P site will be in the middle of the three sites. The order is (3' of mRNA) A site - P site -- E site --(5' of mRNA)
