Which site is the ribosomal binding site for peptidyl-tRNA?

Explanation:
During translation, the tRNA carrying the growing peptide chain sits in the P site. This is where the peptidyl-tRNA resides, holding the polypeptide as it elongates. The A site binds the incoming aminoacyl-tRNA, whose amino acid will be added to the chain. After the peptide bond forms, the ribosome shifts so the peptidyl-tRNA (the growing chain) moves into the P site and the now-empty tRNA leaves through the E site, freeing the A site for the next aminoacyl-tRNA. There isn’t a C site in this system.
