Final answer:
False. The initiation factors IF2 and IF3 do not use the energy of ATP to link the ribosomal subunits. GTP, not ATP, is required for the initiation complex formation.
Step-by-step explanation:
False.
The initiation factors IF2 and IF3 do not use the energy of ATP to link the ribosomal subunits. The initiation complex formation involves the binding of the small ribosomal subunit (30S) to mRNA with the help of initiation factors IF1, IF2, and IF3. However, the energy required for this process comes from GTP, not ATP. GTP-bound eukaryotic initiation factor 2 (GTP-eIF2) is involved in the initiation complex formation in eukaryotes.
