Choose the answer that has these events of translation in the proper sequence. 1. tRNA translocates from the A site to the P site. 2. A small ribosomal subunit binds with the mRNA. 3. Releasing factor binds to the A site. 4. A tRNA binds to the A site. 5. A peptide bond forms between the new amino acid and a polypeptide chain. 2,5,4,3,1 2,4,5,1,3 1,3,2,4,5 4,1,2,5,3 4,1,3,2,5

Choose the answer that has these events of the elongation phase of translation in the proper sequence: 1) A peptide bond forms between the new amino acid and a polypeptide chain. 2) An aminoacyl-tRNA binds to the A site. 3) tRNA leaves the E site. 4) tRNA with an attached polypeptide translocates to the P site. 4, 1, 3, 2 2, 4, 1, 3 4, 3, 2, 1 2, 1, 3, 4 2, 1, 4, 3
