Charged tRNAS enter the ribosome in which site? A site E site O P site

After the polypeptide chain is passed to the next amino acid the uncharged tRNA leaves through this site A site E site  P site

During translational elongation, all tRNA’s enter the ribosome at the A site and exit the ribosome from its E site. Select one:TrueFalse
