The Modified Amino Acid FMet is Essential For

Question

The modified amino acid fMet is essential for
A) bacterial translation.
B) bacterial transcription.
C) eukaryotic transcription.
D) eukaryotic translation.
E) eukaryotic mRNA processing.

Accepted Answer

The modified amino acid fMet (formylmethionine) is essential for bacterial translation. It serves as the initiator amino acid for protein synthesis in bacteria. In contrast, eukaryotes use methionine as the initiator amino acid. Therefore, fMet is not essential for eukaryotic translation or other processes listed in the answer choices.
