The A site, P site, and E site each have specific functions during translation. The A site is responsible for binding incoming tRNAs, the P site retains the growing peptide chain during elongation, and the E site is responsible for the exit of deacylated tRNAs. Therefore, choice A accurately describes the functions of the A site, P site, and E site in order. The other choices either include irrelevant information or inaccurately describe the functions of the sites.

The a Site,P Site,and E Site Each Control ______________ (In
