Ribosomes facilitate specific coupling of tRNA anticodons with mRNA codons during protein synthesis. Which of these processes is not part of the elongation phase of translation?
a.An incoming amino-acid-carrying tRNA s anticodon binds to the complementary triplet codon in the A site
b.An assembled polypeptide on the tRNA in the P site forms a peptide bond with the incoming amino acid in the A site
c.The tRNA with the attached peptide chain is translocated from the A site to the P site
d.The initiator tRNA carrying methionine attaches to the P site
The empty tRNA gets translocated to the E site where it exits the ribosome
