Which step occurs immediately after initiation during translation?

Explanation:
Translation proceeds in stages: initiation, elongation, termination. After initiation, elongation begins. The ribosome, now properly assembled on the mRNA with the initiator tRNA in place, starts decoding each codon: a new aminoacyl-tRNA enters the A site, a peptide bond forms to extend the growing polypeptide, and the ribosome translocates to the next codon. This cycle repeats until a stop codon is reached, triggering termination. DNA replication and transcription are separate processes and do not occur during translation.
