Q. Which of the following orders in the process of translation, is correct?

1. AA enters the ribosome through the E site, binds to the polypeptide chain at the A site and leaves through the P site.
2. AA enters ribosome through P site, binds to the polypeptide chain at E site and leaves through the A site.
3. AA enters the ribosome through A site, binds to the polypeptide chain at P site and exits through the E site.
4. AA enters the ribosome through A site, binds to the polypeptide chain at E site and exits through the P site.
