The bacterial initiator tRNA is fMet-tRNAiMet whereas the eukaryotic initiator tRNA lacks the formyl group on the amino moeity; Met-tRNAiMet. Archaea, which, like bacteria, lack a nucleus, utilize the same initiator tRNA as bacteria, fMet-tRNAiMet in the initiation of translation.

False

Archaea use Met-tRNAiMet in translation initiation, the same as eukaryotes.

The correct answer is "False".

Explanation:

It is false that archaea use the same initiator tRNA as bacteria, in fact archaea use the methionine transfer RNA (Met-tRNAiMet), which is the same initiator that eukaryotic cells use. Other feature that archaea and eukaryotic cells have in common is structural, including that both initiation factors 2 (e/aIF2) are heterotrimeric.
