Which of the following statements explains how N-formylmethionine (fMet) is only associated with the 5' AUG initiation codon and

not with internal AUG codons, given that methionine in both cases in encoded by an AUG in the mRNA. Select all that apply. Group of answer choices Only fMet-tRNA(fMet) can bind first to the P site in the ribosome. There are more than one tRNA with the 5' CAU 3' anticodon. fMet is always incorporated at interior AUG sites and then deformylated after translation. The N-formyl group attached to methionine prevents fMet from entering interior positions in a polypeptide.
