Final answer:
In the initiation of translation in bacteria, the complex formed includes the small ribosomal subunit, mRNA, initiation factors, and initiator tRNA, but not the tRNA carrying the next amino acid for the A site.
Step-by-step explanation:
During the initiation of translation in bacteria, several components come together to form the initiation complex. This complex includes the small ribosomal subunit, the mRNA template, initiation factors, and the initiator tRNA carrying a form of methionine (N-formyl-methionine in prokaryotes). Once this complex is formed, the large ribosomal subunit binds to it, completing the initiation phase. Therefore, the component that is not involved in the initiation of translation is 'B. tRNA carrying the next amino acid that will occupy the A site', because during the initiation phase, only the initiator tRNA that recognizes the start codon is involved.
